Vfp Error 1585
VFP8 Update Conflict with no error 7. Transactions only apply to local tables. The content you requested has been removed. INV2 1 .T. .T. his comment is here
Instead, it returned an ADO recordset with a single row containing a single column named Return_value. Previously, there was no straightforward way to know for sure whether progressive fetching was still in progress, or if all records had been retrieved. Autorefresh_vfp.SCX and Autorefresh_add.SCX use two tables, Autorefresh.DBF and Nextid.DBF, in the Autorefresh.DBC database. One user may have edited the description of a product while another user entered an order for the product, thereby decreasing the quantity on hand.
The CursorAdapter Builder adds code to the Init method of the CursorAdapter to set the recordset’s CursorLocation to 3 (adUseClient). The new getnextmodified() function will tell us exactly what we need to know: the record number for the next modified record. This demonstrates how, once all statement handles on a connection become idle, the physical connection to the database (represented by the connection handle) is dropped. Map remote Unicode data to ANSI in memo fields The new SYS(987, lExpr) function determines whether remote Unicode data is mapped to ANSI in memo fields.
The CursorAdapter Builder has a new Refresh Properties dialog that lets you set values for the auto-refresh properties, using pages 3 and 4. Are you updating a table on SQL server through a remote view or SPT?What does the code look like? Some sequences of transactions however are very sensitive and full commit and rollback functionality may be required. Let’s look at the bank update example but this time use a transaction as a “wrapper” for the update: begin transaction seek M.ACCOUNT1 replace BALANCE with BALANCE - M.AMOUNT seek M.ACCOUNT2
Close Box Join Tek-Tips Today! As a result, the CursorAdapter is not aware of changes made by the remote database, and the VFP cursor will not reflect those new values. Numeric and decimal types can be mapped to VFP Logical only if the scale is zero. When a CursorAdapter uses an ADO recordset as its DataSource, moving the record pointer in the cursor does not move the row pointer in the recordset.
Get count of records affected by SQL Pass-Through SQLEXEC() and SQLMORERESULTS() have a new optional parameter that provides more information on the number of records affected by a SQL command. Commit and rollback is now in operation for the cursor: m.ln_Connect = CURSORGETPROP( 'connecthandle' ) m.ln_Transactions = SQLSETPROP( m.ln_Connect, ; 'transactions', 2) IF NOT m.ln_Transactions == 1 * Error If the record buffer hasn’t changed (the user didn’t edit any fields, add a record, or change the deleted status for the record), tableupdate() returns .T. else = aerror(laError) rollback = messagebox('Error #' + ltrim(str(laError)) + ': ' + laError + ; ' occurred while saving.') endif tableupdate(.T., .T.) Other Issues As we saw earlier, getfldstate() can
Since records can be automatically buffered, there’s no longer a need to use the “manual buffer” mechanism. check over here Timestamp support When you create a remote view with the WhereType property set to 4 (Key and timestamp), VFP automatically determines which field in the remote table is timestamp-compatible and saves In this case, the array is populated with a list of statement handles that share the same connection handle, including nStatementHandle itself. Invalid coordinates (Error 1959) Invalid database table name (Error 1578) Invalid element in XMLTable.Fields collection. (Error 2098) Invalid expression in label definition file (Error 1245) Invalid file descriptor (Error 1111) Invalid
Here are some other concepts regarding transactions: Transactions can only be used with tables attached to databases; free tables need not apply. http://mobilecomment.com/vfp-error/vfp-error-2065.html The RefreshCmdDataSourceType and RefreshCmdDataSource properties are shown for illustration purposes, but do not have to be specified if they are the same as the DataSourceType and DataSource. Why? There appears to be no way to determine whether CursorFill or CursorRefresh completed normally or were cut short by the user pressing Escape.
Be careful to set this inside a form if you are using private data sessions. Figure 3. This might occur where empty values were not permitted for a field in the validation criteria but the program was not able to progress to the user input stage until a weblink The Fields Refresh page allows you to select fields for the RefreshIgnoreFieldList.
If no records are refreshed but there is no error, 0 is returned. getfldstate() is called as follows: if something about the current recorgetfldstate( | [, | ]) and returns one of the following values: Value Description 1 No change 2 The Make sure your update key is valid.
For the STORE_ID field in the SALESVIEW cursor for example: m.lc_Local = salesview.store_id The original value determined when the snapshot of the original data was copied onto the workstation is determined
Then VFP converts the data in the recordset into a cursor. Additional functions exist to help resolve update difficulties. In addition, enhancements to SQL Pass-Through, ADO, and the OLE DB provider give you improved control when accessing remote data. In other words, now we can read directly against the fields in the record and not worry about maintaining memory variables for each one.
lnConn3 = SQLSTRINGCONNECT(lcConnStr) ? "Connection 3 was assigned ODBC connection " ; + TRANSFORM(SQLGETPROP(lnConn3,"ODBChdbc")) ? *-- Execute a query on idle statement handle 2 SQLEXEC(lnConn2, "SELECT * FROM customer") The syntax is: .RecordRefresh( [ nRecords ] [, nRecordOffset ] ) The nRecords parameter specifies the number of records to refresh, in physical order. Autorefresh_sql.SCX, Autorefresh_connect.SCX, and Autorefresh_add.SCX create a new table in the SQL Server Northwind database and use that. check over here showing a message with #processed (step 1.) - #shouldhave processed (step 3.) 6.
Some of the tables involved in the update may be committed in the base remote tables. Usually, SCOPE_IDENTITY() is indeed the better choice because of a limitation of @@IDENTITY. The program might look something like this: seek M.ACCOUNT1 replace BALANCE with BALANCE - M.AMOUNT seek M.ACCOUNT2 replace BALANCE with BALANCE + M.AMOUNT llSuccess = tableupdate(.T.) if not llSuccess do ERROR_ROUTINE If the fields they updated are different, we could tell VFP to just update the field this user changed, leaving the other user’s changes intact.
Update Conflict Error 6. If the FetchMemo property was set to .F., the cursor was retrieved without the memo contents as expected. Table 4. How records are edited in forms is a perfect example of this.
It can be determined with the CURVAL() function: m.lc_Server = CURVAL('store_id') These three functions may be used in combination to check which fields have been changed by the current user or The CursorAdapter Builder has a new Memo Fetching Properties dialog that lets you set values for FetchMemoCmdList, FetchMemoDataSourceType, and FetchMemoDataSource. In this case, we have a “real” conflict. As a result, CustomerID is not included in the RefreshCmd, whose field list must match the field list in the SelectCmd in order, excluding any fields in the RefreshIgnoreFieldList Property.
Unfortunately, the SQL Server ODBC driver executes parameterized inserts using the sp_executesql stored procedure. Introduction If you’ve spent any time at all working with VFP, one of the things you’ve probably learned is that while you can continue to do things the “old” way if That column contained whatever scalar value the stored procedure returned via a RETURN statement, or True if the stored procedure did not contain an explicit return value. Immediately after a successful insert, VFP automatically queries the remote database for a record matching the key values in InsertCmdRefreshKeyFieldList and uses the results to refresh the cursor fields specified in
If you execute SYS(987, .T.) prior to the query, the memo field will contain the ANSI string “It looks like this” instead.
