问题 Using a custom form, fields are updated on a newly created record by an operator. When a new record is created there are fields within that newly created record that are to be updated based on values in another field. For example a field, CustID is updated based on the Primary Key, "PK" as follows: CustID="NW"&Format([PK],"000000") . I can perform this update using an update query however, I would like this update to happen automatically immediately following the creation of the new record. I

问题 In my database I have a table with several yes/no columns. Now, I have a unbound form with some unbound checkboxes and a listbox bound to a special query just for it. I want to use the checkboxes on the form to filter the listbox and display items in the list that have matching values. For example, If I check box1 on the form, any item that contains field1 in the listbox should show. If I check box2 and box3 on the form, any item that contains field2 AND field3 should display in the listbox.

问题 i am dealing with some legacy access < 2007 "databases". All the tables are linked tables to a SQL Server 2008. While the odbc-links are established the table structure is copied into the mdb-file together with the DSN-string. Thats what one can see in Msysobjects. A query forces the jet-engine to retrieve the data from SQL Server under respect of the jet-engines optimization. Therefore it is essential to refresh the odbc-links whenever a change in sql server is made, like adding a new index

问题 I'm trying to connect to my Access database via PHP, but i am getting the following error : Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[IM002] SQLDriverConnect: 0 [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified' in C:\inetpub\wwwroot\agency\getProperty.php:7 Stack trace: #0 C:\inetpub\wwwroot\agency\getProperty.php(7): PDO->__construct('odbc:Driver={Mi...') #1 {main} thrown in C:\inetpub\wwwroot\agency\getProperty.php on

问题 I have the following SQL query that I am trying to run inside Microsoft Access 2010 and I get an error( Syntax error in INSERT INTO statement) then it highlights the field "Level" if I rename the field to "Level1" it works. The problem is that I can't rename the field because I have several SQL queries in PHP that I rely on the field name "Level" Any ideas of why it would throw an error. The reason I am running the query is to copy data from an external ODBC sqlite database using linked

问题 I have 20 text boxes on an Access 2010 form called [P101] to [P110] which refers to fields [P101] to [P110] in the source table. The may contain a value or not, but if not I do not want to see them. I also have a field [UsedFields] in the table which has counted how many of the fields are in use. In Form_Current I can set the following code but is there a way I could set a FOR NEXT loop to use a variable for the Field Name? The current code (which works but is very clumsy) is: If UsedFields >
