问题 Can anyone provide insight into this? I've developed an import process using an XML data type. After the data is inserted in to a table by the import sProc I run another procedures to update another table with the imported table.

Here's the code: DECLARE @xmlRecords XML SET @xmlRecords = (SELECT importedXML FROM importTable WHERE importId = @lastImportId)

问题 I've got a silly situation in my parsec parsers that I would like your help on. I need to parse a sequence of strongs / chars that are separated by | characters. So, we could have a|b|'c'|'abcd' which should be turned into [a,b,c,abcd] Space is not allowed, unless inside of a ' ' string. Now, in my naïve attempt, I got the situation now where I can parse strings like a'a|'bb' to [a'a,bb] but not aa|'b'b' to [aa,b'b]. singleQuotedChar :: Parser Char singleQuotedChar = noneOf "'" <|> try

问题 I have been trying to query two tables in my database. In the server explorer I can see both tables and even see the columns within them. We'll call them Schema.table1 and Schema.table2 where "Schema" has its first letter capitalized. I have tried running the following queries: select * from Schema.table1; Where I get the following error: ERROR: relation "schema.table1" does not exist I then tried running the next query thinking maybe the capitalization in the schema made a difference. Select

问题 I have this rather awkward problem: For two weeks now, whenever after I've updated/created stored procedures using my SQL scripts, when these stored procedures are run, they fail with above error. Other posts dealing with this problem didn't help in my case. Here's a number of parameters, helping to exclude common solutions which do not apply in my case: My stored procedure scripts work flawlessly on my laptop (SQL Server 2012, Windows Server 2008 R2).

问题 I'm totally new in this area please tell me how to fix my problem. when I write this query " SELECT * FROM places " in my database everything is okay. However when I change it to " SELECT * FROM places WHERE eventId=2 ", I get error. Please look at this image. as you can see, eventId column is exist.
