tMSSqlOutput Standard properties
These properties are used to configure tMSSqlOutput running in the Standard Job framework.
The Standard tMSSqlOutput component belongs to the Databases family.
The component in this framework is available in all Talend products.
Basic settings
Database |
Select the desired database type from the list and click Apply. |
Property type |
Either Built-in or
Repository
.
|
Click this icon to open a database connection wizard and store the database
connection parameters you set in the component Basic
settings view. For more information about setting up and storing database connection parameters, see Centralizing database metadata. |
|
Use an existing connection |
Select this check box and in the Component List drop-down list, select the desired connection component to reuse the connection details you already defined. Information noteNote: When a Job contains the parent Job and the child Job, do the following if you
want to share an existing connection between the parent Job and the child Job (for example,
to share the connection created by the parent Job with the child Job).
For an example about how to share a database connection across Job levels, see Sharing a database connection. |
JDBC Provider |
Select the provider of the JDBC driver to be used, either Microsoft (the default, recommended) or Open source JTDS. When Microsoft is selected, you need to download the Microsoft JDBC Driver for SQL Server on Microsoft Download Center, unpack the downloaded zip file, choose a jar in the unzipped folder based on your JRE version, rename the jar to mssql-jdbc.jar and install it manually. For more information about choosing the jar, see the System Requirements information on Microsoft Download Center. Note that OSGi builds will not include any open source jTDS JDBC driver. If you need to build your Job containing this component as an OSGi bundle, use the official Microsoft JDBC driver; otherwise, this component will work only with Datasource with the jTDS JDBC driver properly installed in Talend Runtime. |
Host | Enter the IP address or the hostname of the database server or the Azure Synapse Analytics to be used. If the SQL Server Browser service is running on the machine where the server resides, you can connect to a named instance through a TCP dynamic port by providing the host name and the instance name in this field in the format of {host_name}\{instance_name}. In this case, you can leave the Port field empty. See SQL Server Browser service for related information. |
Port | Enter the listening port number of the database server or the Azure Synapse Analytics to be used. If the SQL Server Browser service is running on the machine where the server resides, you can connect to a named instance through a TCP dynamic port by providing the host name and the instance name in the Host field and leave this field empty. See SQL Server Browser service for related information. |
Schema |
Enter the name of the database schema. |
Database |
Enter the name of the database. |
Username and Password | Enter the authentication data. To enter the password, click the [...] button next to the Password field, enter the password in double quotes in the pop-up dialog box, and then click OK. You can use Type 2 integrated authentication on Windows by adding integratedSecurity=true in the Additional JDBC Parameters field and leave these two fields empty. See section Connecting with integrated authentication On Windows at Building the connection URL for related information. |
Table |
Enter the name of the table to be written. Note that only one table can be written at a time. |
Action on table | On the table defined, you can perform one of the following operations: Default: No operation is carried out. Drop and create table: The table is removed and created again. Create table: The table does not exist and gets created. Create table if not exists: The table is created if it does not exist. Drop table if exists and create: The table is removed if it already exists and created again. Clear table: The table content is deleted. Truncate table: The table content is deleted. You do not have the possibility to rollback the operation. |
Turn on identity insert | Select this check box to use your own sequence for the identity value of the inserted records (instead of having the SQL Server pick the next sequential value). |
Action on data | On the data of the table defined, you can perform: Insert: Add new entries to the table. If duplicates are found, job stops. Single Insert Query: Add entries to the table in a batch
Update: Make
changes to existing
entries.
Information noteNote: In cases where all the schema
columns are set as keys, this action yields an error and the Job fails.
Insert or
update: Insert a new record. If the record with the given reference
already exists, an update would be
made.
Information noteNote: In cases where all the schema
columns are set as keys, this action yields a warning message and the Job
continues.
Update or
insert: Update the record with the given reference. If the record does
not exist, a new record would be
inserted.
Information noteNote: In cases where all the schema
columns are set as keys, this action yields a warning message and the Job
continues.
Delete: Remove entries corresponding to the input flow. Insert if not exist : Add new entries to the table if they do not exist. Information noteWarning: It is
necessary to specify at least one column as a primary key on which the
Update and Delete operations are based. You can do that by clicking
Edit Schema and selecting the check
box(es) next to the column(s) you want to set as primary key(s). For an
advanced use, click the Advanced
settings view where you can simultaneously define primary keys
for the Update and Delete operations. To do that: Select the
Use field options check box and then
in the Key in update column, select the
check boxes next to the column names you want to use as a base for the Update
operation. Do the same in the Key in
delete column for the Delete operation.
Information noteNote: The dynamic schema feature can be used
in the following modes: Insert;
Update; Insert or update; Update or
insert; Delete.
|
Specify identity field | Select this check box to specify the identity field, which is made up of an
automatically incrementing identification number. When this check box is selected, three other fields are displayed: Identity field: select the column you want to define as the identity field from the list. Start value: type in a start value, used for the very first row loaded into the table. Step: type in an incremental value, added to the value of the previous row that was loaded. This check box is available only when you select Drop and create table, Create table, Create table if not exists, or Drop table if exists and create from the Action on table list , and will disappear if you select the Enable parallel execution check box in the Advanced settings view. If you select this check box with the Turn on identity insert check box cleared and the Create table if not exists option selected from the Action on table list and if the specified table does not exist, only a table will be created without inserting data into it. Information noteNote: You can also specify the identity field
from the schema of the component. To do so, set the DB Type of the relevant column to INT IDENTITY.
Information noteNote: When the Specify identity field check box is selected,
the INT IDENTITY DB Type in the schema
is ignored.
|
Schema and Edit schema |
A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. When you create a Spark Job, avoid the reserved word line when naming the fields. Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:
This component offers the advantage of the dynamic schema feature. This allows you to retrieve unknown columns from source files or to copy batches of columns from a source without mapping each column individually. For further information about dynamic schemas, see Dynamic schema. This dynamic schema feature is designed for the purpose of retrieving unknown columns of a table and is recommended to be used for this purpose only; it is not recommended for the use of creating tables. Built-In: You create and store the schema locally for this component only. Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs. When the schema to be reused has default values that are integers or functions, ensure that these default values are not enclosed within quotation marks. If they are, you must remove the quotation marks manually. For more information, see Retrieving table schemas. |
Specify a data source alias |
Select this check box and specify the alias of a data source created on the Talend Runtime side to use the shared connection pool defined in the data source configuration. This option works only when you deploy and run your Job in Talend Runtime . This check box is not available when the Use an existing connection check box is selected. |
Data source alias |
Enter the alias of the data source created on the Talend Runtime side. This field is available only when the Specify a data source alias check box is selected. |
Die on error | This check box is selected by default. Clear the check box to skip the row on error and complete the process for error-free rows. If needed, you can retrieve the rows on error via a Row>Rejects link. |
Advanced settings
Additional JDBC parameters |
Specify additional connection properties for the database connection you are creating. The properties are separated by semicolon and each property is a key-value pair. For example, encrypt=true;trustServerCertificate=false; hostNameInCertificate=*.database.windows.net;loginTimeout=30; for Azure SQL database connection. This field is not available if the Use an existing connection check box is selected. |
Authenticate using Azure Active Directory |
Select this option to use Azure Active Directory authentication when establishing the connection. See Azure AD Authentication for related information. This option is only available when Microsoft is selected from the JDBC Provider drop-down list in the Basic settings view. |
Enable always encrypted (Column encryption) | Select this option to use the Microsoft Always encrypted feature to encrypt and protect your
data. To use this option, you need to have previously stored your secrets with
Azure Key Vault:
Some limitations regarding query operations and statements apply to this feature. For the exhaustive list of limitations, see the Microsoft SQL Server documentation. |
Commit every |
Enter the number of rows to be completed before committing batches of rows together into the DB. This option ensures transaction quality (but not rollback) and, above all, better performance at execution. |
Additional Columns | This option is not offered if you create (with or without drop) the DB
table. This option allows you to call SQL functions to perform actions on columns,
which are not insert, nor update or delete actions, or action that require
particular preprocessing.
|
Use field options | Select this check box to customize a request, especially when there is double action on data. |
Ignore date validation | Select this check box to ignore the date validation and insert the data directly into the database for the data types of DATE, DATETIME, DATETIME2, and DATETIMEOFFSET. |
Debug query mode |
Select this check box to display each step during processing entries in a database. |
Support null in "SQL WHERE" statement | Select this check box if you want to deal with the Null values contained in
a DB table. Information noteNote: Make sure that the Nullable check box is selected for the corresponding columns in
the schema.
|
Use Batch |
Select this check box to activate the batch mode for data processing. Information noteNote: If you select the Single Insert
Query option in the Action on
data list, be aware that the batch size must be lower than or
equal to the limit of parameter markers authorized by the JDBC driver
(generally 2000) divided by the number of columns. For more information, see
Limitation below.
|
Batch Size |
Specify the number of records to be processed in each batch. This field appears only when the Use batch mode check box is selected. |
Set Query Timeout | Select this option to set a timeout period for the query or the batch query.
The Job will be terminated if the query or the batch query is timed out. You can
set the timeout period (in seconds) in the Timeout field. Information noteNote:
|
tStatCatcher Statistics | Select this check box to collect log data at the component level. |
Enable parallel execution |
Select this check box to perform high-speed data processing, by treating
multiple data flows simultaneously. Note that this feature depends on the database or
the application ability to handle multiple inserts in parallel as well as the number of
CPU affected. In the Number of parallel executions
field, either:
Note that when parallel execution is enabled, it is not possible to use global variables to retrieve return values in a subJob. Information noteWarning:
|
Global Variables
Global Variables |
NB_LINE: the number of rows processed. This is an After variable and it returns an integer. NB_LINE_UPDATED: the number of rows updated. This is an After variable and it returns an integer. NB_LINE_INSERTED: the number of rows inserted. This is an After variable and it returns an integer. NB_LINE_DELETED: the number of rows deleted. This is an After variable and it returns an integer. NB_LINE_REJECTED: the number of rows rejected. This is an After variable and it returns an integer. QUERY: the query statement processed. This is an After variable and it returns a string. ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box. A Flow variable functions during the execution of a component while an After variable functions after the execution of the component. To fill up a field or expression with a variable, press Ctrl+Space to access the variable list and choose the variable to use from it. For more information about variables, see Using contexts and variables. |
Usage
Usage rule | This component offers the flexibility benefit of the DB query and covers all
of the SQL queries possible. This component must be used as an output component. It allows you to carry out actions on a table or on the data of a table in a MSSql database. It also allows you to create a reject flow using a Row>Rejects link to filter data in error. For an example of tMysqlOutput in use, see Retrieving data in error with a Reject link. |
Dynamic settings |
Click the [+] button to add a row in the table and fill the Code field with a context variable to choose your database connection dynamically from multiple connections planned in your Job. This feature is useful when you need to access database tables having the same data structure but in different databases, especially when you are working in an environment where you cannot change your Job settings, for example, when your Job has to be deployed and executed independent of Talend Studio. The Dynamic settings table is available only when the Use an existing connection check box is selected in the Basic settings view. Once a dynamic parameter is defined, the Component List box in the Basic settings view becomes unusable. For examples on using dynamic parameters, see Reading data from databases through context-based dynamic connections and Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic settings and context variables, see Dynamic schema and Creating a context group and define context variables in it. |
Limitation | When the Single Insert Query option
is selected in the Action on data list, an
SQL Prepared Statement is generated, for example,
INSERT INTO table (col1, col2, col3) VALUES (?,?,?) ,
(?,?,?) , (?,?,?) ,(?,?,?)
. Within brackets are the groups of parameters the number of which cannot
exceed 2000, generally, depending on the JBDC driver. Therefore, the batch size
should be set so that this limit is respected. Due to license incompatibility, one or more JARs required to use this component are not provided. You can install the missing JARs for this particular component by clicking the Install button on the Component tab view. You can also find out and add all missing JARs easily on the Modules tab in the Integration perspective of Talend Studio. For details, see Installing external modules. |
