foxpro sqlexec error Red Hook, New York

Once executed, the plan is stored in the database along with the procedure itself. Hence the second bit of TRANSACT-SQL code which calls the catalog stored procedure SP_BINDRULE. Stored procedures A stored procedure is a pre-compiled set of Transact-SQL statements. Result Sets With Visual FoxPro, we no longer have to update remote data by issuing SQL commands directly to the server through SQL pass-through.

However, when the problems seem to be outside of Visual FoxPro, SQL Server and ODBC both provide some good tools for watching all of the activity generated by your Visual FoxPro Other users on the network may have changed the data after the table was opened or the cursor was created. We'll start by providing an overview of the installation proce... The Event Class column describes the server event.

Figure 2 shows a simple trace created by opening a view of the Tastrade category table created by the SQL Server Upsizing Wizard in Chapter 5, "Upsizing: Moving from File-Server to fail> > How to cope with this? The first is to search for the constraint name (in this case, CK authors au_id 08EA5793) and present a friendly message for each. In non-batch mode, SQLMoreResults( ) should be called after each successful SQLExec( ) call until SQLMoreResults( ) returns 2 (no more data found).

As with the connection properties, there are two built-in function to assist with the setting of cursor properties: CursorSetProp() and CursorGetProp(). The following stored procedure will actually create a remote view containing a list of company names, total number of orders and sales rep commissions by customer for a user (or program) Even if you are not using a DSN, you can also use the Tracingtab to enable an ODBC trace (see Figure 5). Updating remote data sources is the final topic for this session.

Therefore, you can use the ODBC log to produce a high level of detail on how Visual FoxPro is communicating through the ODBC driver to talk to SQL Server.

The return of -1 is notreally an error as far as FoxPro is concerned. Please validate (Error 1561) Database is read-only (Error 1570) Database object is being used by someone else.

When applied to native data, an update conflict occurs even if the two users edited different fields. If you change the value of a global setting, new connections will be opened with the changed value. Without proper access, you will have a tough time determining the current status of any rules, stored procedures and so on. This allows you to go so far as to show the user what changes were made by the other user and let them evaluate how to proceed.

A second approach to error handling is a radical change over this first approach: Do not update the data on the server through views, but use stored procedures instead. For instance, to find the environment (or new connection default) for transactions you would run this line of code: ?SQLGetProp(0, “Transactions”) Note A connection handle of zero (0) indicates that you Instead of using the actual Text data, the statement provided a unique value for the Text field. SQLConnect() The SQLConnect() function establishes a connection to a data source in one of two ways.

Finally, changes are discarded in the table or cursor open in the currently selected work area if TABLEREVERT( ) is issued without the optional TableAlias or WorkArea arguments. Table "alias" cannot be opened.

The first reports the violation of the CHECK constraint, and the second tells you that SQL Server has terminated the statement. To find out the current setting of a cursor’s properties, you use the CursorGetProp() function. The arguments required for the SQLColumns() function include the connection handle, the name of the remote source table whose column information is being requested, the format for the column information in The alternative is to have no UI; It does what it needs to do without the help of a user.

Furthermore, the time required to generate an execution plan only occurs the first time the procedure is run. Another great use for the Profiler is as a learning tool.

You can include expressions in the SQL statement.

Any suggestions on how to handle this error?Thanks mike 2004-09-30 13:33:04 UTC PermalinkRaw Message Hey Cindy,I am getting a return of -1, so I guess the SQL Server is returning theerror. Recall that TABLEUPDATE() can detect update conflicts with its second parameter set to False.

Clearly, the additional time is required to report the wealth of information produced by the ODBC trace to the log--the resulting log file is 178K! However, when dealing with remote data, CURVAL() is worthless, as it always returns the same value as OLDVAL(). When manual transactions are in effect (the SQLSetProp( ) Transactions property is set to manual), you can send multiple updates to remote tables and commit all the updates with SQLCommit( ). Most of these errors will be among those listed in Table 3.

You can find out all sorts of neat things by trying a function in the Enterprise Manager or from Visual FoxPro, and then looking at the Profiler to see what happened. This department claims ownership of the server and the associated database that you need to access in order to write your Visual FoxPro application. Rules are evaluated whenever the user attempts to INSERT or UPDATE a value. Then it follows that the query is showing some error (-1 return code).

If table buffering is enabled, changes made to all records are committed to the table or cursorIf row buffering is enabled, only changes made to the current row in the table Copy SQLSETPROP(gnConnHandle, 'asynchronous', .F.) SQLEXEC(gnConnHandle, 'SELECT * FROM authors', 'MyCursor') Example 2 The following example assumes SQLCONNECT( ) is successfully issued, and its return value is stored to a memory variable A third alternative is to not use any data validations on the server at all, and instead handle all of them from within the client application.
