My procedure has large query syntax, many "nested if else" when I create it on one SQL Server I get this error:
Some part of your SQL statement is nested too deeply. Rewrite the query or break it up into smaller queries.
but when I create that on another server, it is created without error. I know the procedure has poor performance but why that is created correctly on another server
Does it depend on server config or database feature ?
when i create that on another server,that is created without error
Reason is that the two version is not same . I think you 1st server is older than 2012sp1 that's why you got that error. you can check this link

I am a new database intern working with a access front end and SQL server backend database. The database was custom made for the company. One of my assignments is to take scripts and apply them to make four new tables. I am aware that I need to make a new query for each new table but I don't know if I should make the query in SQL server management studio or the frontend access program. I have tried copying and pasting the given scripts into a new query in access but I get an error message "invalid SQL statement expected 'DELETE', 'INSERT'...". I decided to try to break done the program a little bit and tested the first line
IF EXISTS (SELECT * FROM sys.foreign_keys WHERE object_id =OBJECT_ID(N'[dbo] .[FK_tblInstrumentInterfaceLog_tlkpInstrument]') AND parent_object_id = OBJECT_ID(N'[dbo].[tblInstrumentInterfaceLog]'))
but the same error message keeps popping up. I even tried just SELECT * FROM sys.foreign_keys, and I got the error message "could not find file...". I am very much a beginner and any guidance would be appreciated.Basically am I supposed to be applying these scripts the server SQL database or on the front end access program?
Are you using a pass-through query? i.e. not just a select query. Access needs to know where to send the query and since you are using TSQL not Access SQL this needs to be executed on the server.
Normally when you query a linked table the information of how to get the data (the connection string) is tied to the table. But for this kind of query you'll probably need to tell Access explicitly. Unless you are using an ADP/ADE, then the connection info travels with the program not the table.
As a general rule, you use SQL management studio (SSMS) to create and run those scripts. So the general accepted approach here is such scripts will not be placed in the front end. As noted such scripts if for some reason must be placed in the front end, then you have to create them as pass-though, but EVEN in this case you want to use the SSMS to create such quires.
So the answer here is you create the new scripts and make table queries in the back end, or in this case using the SQL server management studio.
The syntax checking, query editor etc. in recent versions of SSMS now has auto-complete etc. and you can test/write/update those scripts in SQL server. Once you have such a query or even several of them, then the resulting “several” statements can be pasted into a front end query that been created as pass-though. If you do not use a pass-though query, then you are creating and using and assuming client side SQL (JET (now called ACE)).
The client side has it own version of SQL syntax, and it is NOT 100% compatible with the SERVER SIDE. If you writing SQL in the client that is NOT pass though, then you using a linked table to SQL server. These linked tables thus will use local (JET/ACE) based SQL queries. The ODBC driver thus translates this SQL into server side compatible syntax. However the JET/ACE sql syntax is very limited when compared to SQL server and no server side commands exist in this SQL syntax for the client data engine (JET/ACE)
So for many quires, you will and can simply build such queries using the Access query builder.
However for SQL that needs to run 100% server side then such quires has to be setup as pass-though and are in most cased built + tested using SSMS.
I need to get each statement of given SQL Server stored procedure.
To achieve this, I generate execution plan XML and look for "StmtSimple" nodes in query.
This approach is quite slow for large procedures.
Is there any way that I can get every single statement of the procedure without generating XML execution plan?
When you have the text of a stored procedure, you can perform a full parse on it using the TransactSql ScriptDom. If you just want to get each statement, it's possible to do that using this method.
However, I'm not convinced that it would actually perform much better than using the method you are using now. It's just another option to try.
Edit -> The ScriptDom is part of the SQL Server 2012 Feature Pack, and is contained in the 'SqlDom.msi' install.
I am trying to insert rows into a MySQL database from an Access database using SQL Server 2008 SSIS.
TITLE: Microsoft SQL Server Management Studio
------------------------------
ERROR [42000] [MySQL][ODBC 5.1 Driver][mysqld-5.0.51a-community-nt]You have
an error in your SQL syntax; check the manual that corresponds to your MySQL
server version for the right syntax to use near '"orders"' at line 1
The problem is with the delimiters. I am using the 5.1 ODBC driver, and I can connect to MySql and select a table from the ADO.Net destination data source.
The MySql tables all show up delimited with double-quotes in the SSIS package editor:
"shipto addresses"
Removing the double quotes from the "Use a table or view" text box on the ADO.NET Destination Editor or replacing them with something else does not work if there is a space in the table name.
When SSIS puts the Insert query together, it retains the double quotes and adds single quotes.
The error above is shown when I click on "Preview" in the editor, and a similar error is thrown when I run the package (albeit then from the actual insert statement).
I don't seem to have control over this behavior. Any suggestions? Other package types where I can hand-code the SQL don't have this problem.
Sorry InnerJoin, I had to take the accepted answer away from you. I found a workaround here:
The solution is to reuse the connection for all tasks, and to turn ANSI quotes on for the connection before you do any inserts, with an Execute Sql task that runs the following:
set sql_mode='STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,
NO_ENGINE_SUBSTITUTION,ANSI_QUOTES'
Try using square brackets around the table names. That may help.
EDIT: If you can, I would create views (with no spaces) based on the Access tables, and use those to export. Even if it means building another Access database with linked tables, I think this is your best bet.
I've always struggled with using SSIS with MYSQL directly. Even after installing the ODBC drivers, they just don't play well in data flows. I've always ended up creating linked ODBC connections between SQL Server and MYSQL. I then rely on linked server queries to bring over data. Instead of using a SSIS data flow task, I use an Execute SQL command, usually in the form of a stored procedure that executes an OPENQUERY.
One solution you could do is load the data into a SQL Server database and use it as a staging environment before you load it into the MYSQL database. I regularly move data between SQL Server 2008 and MYSQL and in the past I use to regularly move data between Access and SQL Server.
Another possible solution is to transform the incoming Access data before it loads into the MYSQL database. That may give you a chance to clean up the column names and the actual data that's going through to MYSQL.
Let me know if either of these work for you.
You can locate the configuration setting file my.ini at <<Drive>>:\ProgramData\MySQL\MySQL Server 5.6\my.ini and add "ANSI_QUOTES" to sql-mode.
e.g: sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION,ANSI_QUOTES". This should solve the issue while previewing in the SSIS editor.
What is a dynamic SQL query, and when would I want to use one? I'm using SQL Server 2005.
Here's a few articles:
Introduction to Dynamic SQL
Dynamic SQL Beginner's Guide
From Introduction to Dynamic SQL:
Dynamic SQL is a term used to mean SQL code that is generated programatically (in part or fully) by your program before it is executed. As a result it is a very flexible and powerful tool. You can use dynamic SQL to accomplish tasks such as adding where clauses to a search based on what fields are filled out on a form or to create tables with varying names.
Dynamic SQL is SQL generated by the calling program. This can be through an ORM tool, or ad-hoc by concatenating strings. Non-dynamic SQL would be something like a stored procedure, where the SQL to be executed is predefined. Not all DBA's will let you run dynamic SQL against their database due to security concerns.
A dynamic SQL query is one that is built as the program is running as opposed to a query that is already (hard-) coded at compile time.
The program in question might be running either on the client or application server (debatable if you'd still call it 'dynamic') or within the database server.
I have written SQL statements (stored in a text document) that load data into a SQL Server database. These statements need to be repeated daily. Some of the statements use the NewId() function to populate a keyed field in the database, and this works fine.
While I'm in the process of writing an application to replicate these statements, I want to use Access queries and macros instead of copying and pasting queries into SQL Server, thus saving me time on a daily basis. All is working fine but I can't find any function that will replace the SQL Server NewId() function. Does one exist or is there a work around?
I'm using SQL Server 2005 and Access 2007.
On top of matt's answer, you could simply use a pass-through query and just use your existing, working queries from MS Access.
A solution would be to insert the stguidgen() function in your code, as you can find it here: http://trigeminal.fmsinc.com/code/guids.bas https://web.archive.org/web/20190129105748/http://trigeminal.fmsinc.com/code/guids.bas
The only workaround I can think of would be to define the column in your access database of type "Replication ID" and make it an autonumber field. That will automatically generate a unique GUID for each row and you won't need to use newid() at all. In SQL server, you would just make the default value for the column "newid()".
Again, there seems to be confusion here.
If I'm understanding correctly:
You have an Access front end.
You have a SQL Server 2005 back end.
What you need is the ability to generate the GUID in the SQL Server table. So, answers taht suggest adding an AutoNumber field of type ReplicationID in Access aren't going to help, as the table isn't a Jet table, but a SQL Server table.
The SQL can certainly be executed as a passthrough query, which will hand off everything to the SQL Server for processing, but I wonder why there isn't a default value for this field in SQL Server? Can SQL Server 2005 tables not have NewId() as the default value? Or is there some other method for having a field populate with a new GUID? I seem to recall something about using GUIDs and marking them "not for replication" (I don't have access to a SQL Server right at the moment to look this up).
Seems to me it's better to let the database engine do this kind of thing, rather than executing a function in your SQL to do it, but perhaps someone can enlighten me on why I'm wrong on that.
