SQL Tools Functional Families

Elke SQL Tools functie is toegewezen aan een 'familie' om eenvoudiger overeenkomstige functies te vinden. Elke bladzijde van het Help-bestand geeft de familie van de functie aan, zodat u eenvoudig soortgelijke functies kunt bekijken.

Various utility functions, such as text-to-binary and binary-to-text conversions, a "string interpreter" that simplifies the use of certain characters in strings (such as quotation marks), and a simple Message Box function.


Get Info Family

SQL Tools Internal "Get" Functions. These functions are rarely used in programs because SQL Tools automatically uses these functions (internally) whenever an Info function is used. When an Info function is first used, SQL Tools caches all of the information that is related to the function, for faster access in the future. The Get functions can be used to force SQL Tools to "refresh" the Info data, if you have reason to believe that, while your program is running, a table has been added, a column has been deleted, etc.

SQL_GetTblCols, SQL_GetTableColumns
SQL_GetTblInfo, SQL_GetTableInfo

Handle Family

These functions can be used to obtain certain window handles, plus the actual ODBC handles of the ODBC Environment, each ODBC database connection, and each ODBC statement.


SQL Tools Pro Only...

It should not be necessary to use these functions unless you wish to write API-level functions that SQL Tools does not provide. (Of which there are very, very few.):

SQL_hDatabase, SQL_hDB
SQL_hStatement, SQL_hStmt


(For information about the "duplicate" functions like SQL_OpenDatabase and SQL_OpenDB above, see Two Of Everything.)
