I got around the issue by using a convert on the      so my code looks like convert char 50     and that got rid of the truncation error

Either the parameter supplied for ZIP CODE is larger  in length  than ZIP CODEs column width or the parameter supplied for CITY is larger  in length  than CITYs column width    It would be interesting to know the values supplied for the two   placeholders

I was facing the same issue  So  i created a stored Procedure and defined the size like  FromDate datetime   ToDate datetime   BL varchar 50  After defining the size in  BL varchar 50   i did not face any problem  Now it is working fine

This is a known issue of the mssql ODBC driver  According to the Microsoft blog post      The ColumnSize parameter of SQLBindParameter refers to the number of characters in the SQL type  while BufferLength is the number of bytes in the application s buffer  However  if the SQL data type is varchar n  or char n   the application binds the parameter as SQL C CHAR or SQL C VARCHAR  and the character encoding of the client is UTF-8  you may get a  String data  right truncation  error from the driver even if the value of ColumnSize is aligned with the size of the data type on the server  This error occurs since conversions between character encodings may change the length of the data  For example  a right apostrophe character  U 2019  is encoded in CP-1252 as the single byte 0x92  but in UTF-8 as the 3-byte sequence 0xe2 0x80 0x99    You can find the full article here
