SQLRETURN SQLGetStmtAttr(SQLHSTMT StatementHandle, SQLINTEGER Attribute, SQLPOINTER ValuePtr, SQLINTEGER BufferLength, SQLINTEGER *StringLengthPtr);
La valeur de l'option est lue dans par le paramètre ValuePtr de taille BufferLength. Eventuellement, la taille de sortie est rangée dans le paramètre StringLengthPtr.
Voici les attributs usuels :
Le résultat est SQL_SUCCESS en cas de succès.
