This page is part of the book SQL-99 Complete, Really, by Peter Gulutzan & Trudy Pelzer. The authors have graciously allowed us to reproduce the contents of the book here. Because the book is about the SQL-99 standard, the contents of this and other pages in the book may not directly apply to MariaDB. Use the navigation bar to navigate the book.

Here are the type definitions in the sqlcli.h header file. We use these names for declarations of C variables in all our examples.

typedef unsigned char  SQLCHAR;      /* 8-bit-octet strings */
typedef long int       SQLINTEGER;   /* 32-bit, signed */
typedef short int      SQLSMALLINT;  /* 16-bit, signed */
typedef float          SQLREAL;      /* see heading: IEEE */
typedef double         SQLDOUBLE;    /* see heading: IEEE */
typedef void*          SQLPOINTER;   /* pointer, untyped */
typedef long int       SQLHENV;      /* 32-bit env handle */
typedef long int       SQLHDBC;      /* 32-bit dbc handle */
typedef long int       SQLHSTMT;     /* 32-bit hstmt handle */
typedef long int       SQLHDESC;     /* 32-bit desc handle */

Note: In the ODBC 3.0 header file, SQLHENV and SQLHDBC and SQLHSTMT and SQLHDESC are all "typedef void*" instead of "typedef long int". In older versions of the ODBC header file, the names were HENV, HDBC, HSTMT, etc.
