ANSI_BLANKS option [compatibility]

Function 

Controls behavior when character data is truncated at the client side.

Allowed values 

ON, OFF

Default 

OFF

ON for Open Client and JDBC connections

Description 

The ANSI_BLANKS option has no effect unless the database was created with the -b command-line option. It forces a truncation error whenever a value of data type CHAR(N) is read into a C char(M) variable for values of N greater than or equal to M. With ANSI_BLANKS set to OFF, a truncation error occurs only when at least one non-blank character is truncated.

For Embedded SQL, if ANSI_BLANKS is ON when you supply a value of data type DT_STRING, you must set the sqllen field to the length of the value, including space for the terminating null character. With ANSI_BLANKS off, the length is determined solely by the position of the null character.

The ANSI_BLANKS setting persists for the life of a connection. Changing it after a connection has been established does not affect that connection.
