问题 This is building on some code I got the other day (thanks to peterm). I am now trying to select the TOP X number of results after calculations on the query. The X can range from 1 to 8 depending on the number of results per player. This is the code I have but I get a syntax error when I try to run it. SELECT PlayerID , RoundID , PlayedTo , (SELECT Count(PlayerID) FROM PlayedToCalcs) AS C , iif( C <= 6 , 1 , iif( C <= 8 , 2 , ( iif( C <= 10 , 3 , ( iif( C <= 12 , 4 , ( iif( C <= 14 , 5 , ( iif

问题 We are currently using Access 2003. I have a vehicle maintenance log which has a text field for vehicle numbers. The field needs to be text as it will have a R in it when a vehicle is retired. They would like to have the field be a four digit number with leading zero's. So vehicle 22 would be displayed in the table and reports as 0022 and when retired it would be R0022. I have tried to change the format of the field to "0000" and "0000"# but neither of these will display the leading zero's.

问题 I have the following data that I want to create a crosstab query: ID CallNo CopyrightYear 1 AH 2000 2 AB 2000 3 BC 2000 4 AH 2002 5 ZA 2005 6 BC 2001 7 AP 2003 This is the crosstab query that I currently have: TRANSFORM Count(Table1.[ID]) AS CountOfID SELECT Table1.[CallNo], Count(Table1.[ID]) AS [Total Of ID] FROM Table1 GROUP BY Table1.[CallNo] PIVOT Table1.[CopyrightYear]; So my question is on how can I group copyright year like from 2000 to 2002 and 2003 to 2005 and so on...

问题 I am getting the following error message... "The SQL statement could not be executed because it contains ambiguous outer joins. To force one of the joins to be performed first, create a separate query that performs the first join and then include that query in your SQL statement." HOW CAN I FIX THIS??? If i replace the "LEFT JOIN" with "INNER JOIN" the bug goes away but the desired operation is not accomplished. Here is my code: SELECT route.productfam, facility.location, asmlines.line,

问题 I've been successfully using SELECT [field] FROM [Table] IN 'Network Location'; this question filled me in on that Access SQL Query from another DB My question is: How does a JOIN fit into this framework Is it SELECT [field] FROM [Table] IN 'Network Location' JOIN [Table2] ON [Table2].field = [Table].field; or SELECT [field] FROM [Table] JOIN [Table2] ON [Table2].field = [Table].field IN 'Network Location' ; it feels like the former is the correct one. SQL statements are supposed to be like

问题 I have a linked table, tblREDEIMPORT that is set to a specific path that's only accessible programatically through a FSO import process where it overwrites the previous day's version. However, while the .xls linked file is always named the same thing, the name of the sheet that it's on changes every day giving me an error like 215380_REDEFILEIMPORTREPORT_230$ is not a valid name, because that was yesterdays sheet name, todays sheetname has a completely different set of numbers before and

问题 I was running VSExpress 2010 C# and SQLExpress 2008 on 32b XP. Due to a failure I am now on Win7 64bit. I have reinstalled VSExpress C# (64b).

(I have downloaded it but
