The SQLVAR Array
The SQL Reference Guide discusses the legal values of the sqlvar array. The describe and prepare into statements assign type, length, and name information into the SQLDA. This information refers to the result columns of a prepared select statement, the fields of a form, or the columns of a table field. When the program uses the SQLDA to retrieve or set Ingres data, it must assign the type and length information that now refers to the variables being pointed at by the SQLDA.
