The Store statement creates a QVD, Parquet, CSV, or TXT file.
Syntax:
Store [ fieldlist from] table into filename [ format-spec ];
The statement will create an explicitly named QVD, Parquet, or text file.
The statement can only export fields from one data table. If fields from several tables are to be exported, an explicit join must be made previously in the script to create the data table that should be exported.
The text values are exported to the CSV file in UTF-8 format. A delimiter can be specified, see LOAD. The store statement to a CSV file does not support BIFF export.
Arguments:
| Argument | Description |
|---|---|
| fieldlist::= ( * | field) { , field } ) |
A list of the fields to be selected. Using * as field list indicates all fields. field::= fieldname [as aliasname ] fieldname is a text that is identical to a field name in table. (Note that the field name must be enclosed b straight double quotation marks or square brackets if it contains spaces or other non-standard characters.) aliasname is an alternate name for the field to be used in the resulting QVD or CSV file. |
| table | A script label representing an already loaded table to be used as source for data. |
| filename |
The name of the target file including a valid path to an existing folder data connection. Example: 'lib://Table Files/target.qvd' In legacy scripting mode, the following path formats are also supported:
|
| format-spec ::=( ( txt | qvd | parquet), compression is codec) |
You can set the format specification to either of these file formats. If the format specification is omitted, qvd is assumed.
If you use parquet, you can also set which compression codec to use with compression is. If you do not specify the compression codec with compression is, snappy is used. The following compression settings are available:
Example: Store mytable into [lib://DataFiles/myfile.parquet] (parquet, compression is lz4); |
Examples:
Store mytable into xyz.qvd (qvd);
Store * from mytable into 'lib://FolderConnection/myfile.qvd';
Store Name, RegNo from mytable into xyz.qvd;
Store Name as a, RegNo as b from mytable into 'lib://FolderConnection/myfile.qvd';
Store mytable into myfile.txt (txt);
Store mytable into myfile.parquet (parquet);
Store * from mytable into 'lib://FolderConnection/myfile.qvd';
