[!INCLUDESQL Server Azure SQL Database Synapse Analytics PDW]
Sets the total number of columns found in the user file for use with a bulk copy into or out of [!INCLUDEssNoVersion]. bcp_setbulkmode can be used instead of bcp_columns and bcp_colfmt.
RETCODE bcp_columns (
HDBC hdbc,
INT nColumns);
hdbc
Is the bulk copy-enabled ODBC connection handle.
nColumns
Is the total number of columns in the user file. Even if you are preparing to bulk copy data from the user file to an [!INCLUDEssNoVersion] table and do not intend to copy all columns in the user file, you must still set nColumns to the total number of user-file columns.
SUCCEED or FAIL.
This function can be called only after bcp_init has been called with a valid file name.
You should call this function only if you intend to use a user-file format that differs from the default. For more information about a description of the default user-file format, see bcp_init.
After calling bcp_columns, you must call bcp_colfmt for each column in the user file to completely define a custom file format.
