lrd_bind_col

Example: lrd_bind_col Statement Handling Functions

Binds a host variable to a column.

LRDRET lrd_bind_col( LRD_CURSOR *mptCursor, int muiColNum, LRD_VAR_DESC *mptVarDesc, long mliOption, int miDBErrorSeverity);

mptCursor A pointer to an LRD_CURSOR structure.
muiColNum The column number in the result set.
mptVarDesc A pointer to the descriptor of a variable to bind.
mliOption A database dependent option (NULL).
miDBErrorSeverity The Error Severity Levels of a failure in a database routine.

A host variable is automatically generated by VuGen. It has the following structure:

<column name>_D<data index>

For example, &ENAME_D3 represents the third set of data whose column name is "ENAME".

The lrd_bind_col function binds a host variable to an output column. VuGen generates an lrd_bind_col statement for all columns in the result set.

For more details refer to the Function Header File lrd.h in the include directory.
