DOCUMENT:Q104342 01-NOV-2001 [foxpro] TITLE :SQL Server System Funcs Supported by the Connectivity Kit PRODUCT :Microsoft FoxPro PROD/VER::2.6a,3.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual FoxPro for Windows, version 3.0 - Microsoft FoxPro for MS-DOS, version 2.6a - Microsoft FoxPro for Windows, version 2.6a ------------------------------------------------------------------------------- SUMMARY ======= The Microsoft FoxPro Connectivity Kit can be used with FoxPro versions 2.5x for MS-DOS and Windows. The FoxPro Connectivity Kit, and the Open Database Connectivity (ODBC) specification in general, supports the minimum ANSI SQL standard. Below is a list of the SQL System functions that are supported. In FoxPro 2.6x and Visual FoxPro 3.0, the Connectivity Kit is included in the Professional Edition. MORE INFORMATION ================ The following table lists the supported System functions. Parameter arguments denoted as can be the name of a column, the result of another scaler function, or a literal, where the underlying data type could be represented as SQL_NUMERIC, SQL_DECIMAL, SQL_TINYINT, SQL_SMALLINT, SQL_INTEGER, SQL_BIGINT, SQL_FLOAT, SQL_REAL, SQL_DOUBLE, SQL_DATE, SQL_TIME, or SQL_TIMESTAMP. Parameter arguments listed as can be a literal constant, where the underlying data type can be represented as SQL_NUMERIC, SQL_DECIMAL, SQL_TINYINT, SQL_SMALLINT, SQL_INTEGER, SQL_BIGINT, SQL_FLOAT, SQL_REAL, SQL_DOUBLE, SQL_DATE, SQL_TIME, or SQL_TIMESTAMP. Values returned are represented as ODBC data types. Function Description -------------------------------------------------------------------- USER() Returns the user's authorization name. (The user's authorization name is also available via SQLGetInfo by specifying the information type SQL_USER_NAME.) DATABASE() Returns the name of the database corresponding to the connection handle (hdbc). (The name of the database is also available via SQLGetInfo by specifying the information type SQL_DATABASE_NAME.) IFNULL(exp,value) If is null, is returned. If is not null, is returned. The possible data type(s) of must be compatible with the data type of . Following is an example of how the USER() function could be used from within FoxPro to return the user's authorization name. This example assumes that a valid connection to an ODBC data source has already been established and that the connection handle is contained in the variable mhand: FoxPro 2.x Example ------------------ result=DBEXEC(mhand, "SELECT {FN USER()}","output") Visual FoxPro Example --------------------- result=SQLEXEC(mhand, "SELECT { FN USER() }", "output") REFERENCES ========== Microsoft Open Database Connectivity Software Development Kit (SDK) "Programmer's Reference," version 1.0, page 530 Additional query words: FoxWin FoxDos VFoxWin CK 2.50 2.50a 2.50b 2.60 2.60a ====================================================================== Keywords : Technology : kbVFPsearch kbAudDeveloper kbFoxproSearch kbZNotKeyword3 kbFoxPro260aDOS kbFoxPro260a kbVFP300 Version : :2.6a,3.0 ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
