Table labels


Table labels

A table can be labeled for later reference, for example by a LOAD statement with a resident clause or with expressions containing the peek function. The label, which can be an arbitrary string of numbers or characters, should precede the first LOAD or SELECT statement that creates the table. The label must be followed by a colon ":".

Labels containing blanks must be quoted using single or double quotation marks or square brackets.

Example 1:  


LOAD a,b from c.csv;

LOAD x,y from d.csv where x=peek('a',y,'Table1');

Example 2: Table label containing a blank

[All Transactions]:

SELECT * from Transtable;

LOAD Month, sum(Sales) resident [All Transactions] group by Month;
