handleIdent_Int | in | Identifier of Int type (handle) of the connection to the database (DB_CONNECT). |
lobColNameIdent_Str | in | Name of a column of LOB type in the table. |
lobFileNameIdent_Str | in | Name of a file, where the LOB type record read is to be written. |
transHandle_Int | in | Identifier of the Connection to the database. |
idKeyIdent | in | Identification key determining the row (if the key consists of several columns, idKeyIdent is a structure of the same type as the table - just values of key columns are to be taken into account). |
strExpression_Str | in | Expression of String type, that defines the table row read. |
dbObjIdent | in | Reference to an object of Database table type. |
retCodeIdent_Int | out | Return code of Int type - action success. |
hintIdent_Str | in | Expression of String type that defines Oracle SQL hint.
It is used as an instruction for the performance optimizer of SQL
command. The value is used without the opening and
terminating characters /*+ <orahint>
*/. The example is mentioned here. |
A row, which will be read, can be defined:
The parameter retCodeIdent_Int returns the attribute _ERR_NO_ERROR - action success, or:
