Fetch CHAR data

An application can fetch data from a database column of type CHAR or VARCHAR into a character (char, string, fixchar, varchar, or lvarchar) host variable. If the column data does not fit into the character host variable, IBM® Informix® ESQL/C truncates the data. To notify the user of the truncation, Informix ESQL/C performs the following actions:

• It sets the sqlca.sqlwarn.sqlwarn1 warning flag to W and the SQLSTATE variable to 01004.
• It sets any indicator variable that is associated with the character host variable to the size of the character data in the column.
