Search Stored Procedures

2008-07-03T15:06:00.002-05:00

This searches all the Stored Procedures in 1 SQL Server database for the said string. I tested it in Query Analyzer and it found all the Stored Procedures that had occurrences of my "lq_Campaign" in 1 database:

SELECT ROUTINE_NAME, ROUTINE_DEFINITION
FROM INFORMATION_SCHEMA.ROUTINES
WHERE ROUTINE_DEFINITION LIKE '%lq_Campaign%'
AND ROUTINE_TYPE='PROCEDURE'

Here is another way

Below query you can searcg any table, stored procedure or views what ever has that expression as a column or object name.

SELECT * FROM SYSOBJECTS WHERE ID IN (SELECT ID FROM SYSCOMMENTS WHERE TEXT LIKE ‘%PRODUC%’)

The query produced all the object names--where ever it finds expression like ‘PRODUC‘.

Model View Controller

2008-07-03T08:28:00.002-05:00

Primary goal is to separate the things that change from the things that do not.
Model is the data representation.
View is the presentation of the model.
Controller responds to events and modifies the model.
Model notifies the views to update the presentation.

SQL Server 2005 Reports: tips

SSIS > VS Export wizard: table to Excel

2008-03-28T17:23:00.027-05:00

After using the SSIS > VS Export wizard for table to Excel, you must add DROP TABLE Query to the Event Handlers tab or else it will error the second time it is reRun.

SSIS > VS Import wizard for Excel to table:

Be sure to only checkmark Results$.
Be sure to Select Delete table option.
Be sure to Change Results$ name to Destination table name.
If there is an error, it is often because a row in Excel has a NULL but the table column is NOT NULL (so add a blank to the Excel field).

Create SSIS to copy tables

2008-03-06T12:28:00.009-06:00

An SSIS to copy tables from a Source to a Destination. Directions:

From Start, select SQL Server Business Intelligence Development Studio
File
1. New Project…
  1. Project types: Business Intelligence Projects
  2. Integration Services Project…
  3. Click “OK”
Toolbox
1. Drag "Transfer SQL Server Objects Task" to "Control Flow" tab's pane.
  1. Right-click choose Edit…
    1. Objects
      1. SourceConnection ‹New connection…› = NWDSQL
      2. SourceDatabase = NIS_empl_wage
      3. DestinationConnection ‹New connection…› = TESTSQL
      4. DestinationDatabase = NIS_empl_wage
      5. CopyData = True
      6. ExistingData = Replace (so not append (dup errors))
      7. ObjectsToCopy (expand)
        
        CopyAllTables = True (so not sprocs)
      8. Note: Leave all other options False. Ex., Table Options—Can leave all these False because it will just move data so Destination’s Primary Keys will remain.
  2. Click “OK”
Save and Run

Note 1: Your Properties for the Transfer SQL Server Objects Task will now look like this:

CopyAllTables = True (so not sprocs)
CopyData = True
DestinationConnection = TESTSQL
DestinationDatabase = NIS_empl_wage
ExistingData = Replace (so not append (dup errors))
SourceConnection = NWDSQL
SourceDatabase = NIS_empl_wage

Note 2: A DB "restore" by the DBA would nix Destination tables that do not exist in Source tables; but not this technique.

--NWDSQL.BmrkSource.PendingPublish is empty for 2003-2004. Thus do this to populate it with rows from the other table:
INSERT INTO BmrkSource.dbo.PendingPublish
SELECT NEArea,IdentifierCode,EndDate,NumberOfPeople,Week,ItemCodeID,Ratio --Note: Published has 1 extra column at the end so I must list these out.
FROM NELausData.dbo.Published
WHERE NELausData.dbo.Published.EndDate LIKE '2004%'
OR NELausData.dbo.Published.EndDate LIKE '2003%'

The INNER JOIN returns all rows from both tables where there is a match. If there are rows in first table that do not have matches in second table, those rows will not be listed.
The LEFT JOIN returns all the rows from the first table, even if there are no matches in the second table. If there are rows in first table that do not have matches in second table, those rows also will be listed.
The RIGHT JOIN returns all the rows from the second table, even if there are no matches in the first table. If there had been any rows in second table that did not have matches in first table, those rows also would have been listed.

How to get a DB and send it....

2007-11-22T14:07:00.000-06:00

You can backup the DB from the server and then restore it on your local machine with installed MS SQL Server 2000. Then you can change or delete any pruned info from the DB on your local machine. Then you can backup the modified DB again and send that backup file (*.bak file). You can send this file with Gmail. There is about 3Gb available space.

How to backup...

Open Enterprise Manager
Select source DB
Right click on the selected DB. Select All Tasks->Backup Database... from the popup menu.
Select File and filegroup and add destination file name in the Backup dialog.
Press OK

How to restore...

Open Enterprise Manager
Select Databases node
Right click on this node. Select All Tasks->Restore Database... from the popup menu.
Type database name in the Restore as database textbox
Select Restore From Device
Press Select Device
Add backup file name
Press OK
In the Options tab check file pathes where your database will be restored.
Press OK
Select File and filegroup and add destination file name in the Backup dialog.
Press OK

Excel: compare two Worksheets

2007-09-27T16:59:00.001-05:00

Excel Macro
http://exceltip.com/st/Compare_two_worksheets_using_VBA_in_Microsoft_Excel/477.html
Compares the 2 Worksheets and pops up a workbook with the differences:
Steps: >Tools > Macro >Macros >Run

Excel Function
Function for comparing data: http://office.microsoft.com/en-us/excel/HP100625641033.aspx?pid=CH100645341033
Here's the Excel formula: =Exact(ColumnRow,ColumnRow)
An example: =EXACT(G5,P5) [First put both worksheets on the same worksheet, side by side.]
If the result is True data matches; if False data does not match

Also, I was told there is a way to recieve as output each row that was different using a "Filter".

SQL compare two tables

2007-08-30T17:37:00.001-05:00

Difference in data stored in both tables (compare the difference between two tables)? You can use SQL to see rows which don't have a match in one table or the other:

Select col_a,col_b from table1 
where not exists 
    (select * from table2 
     where table1.col_a = table2.col_a and 
           table1.col_b = table2.col_b)

Repeat for table2.

Debug sproc in VS

2007-07-20T09:30:00.000-05:00

In VS at the Sever Explorer pane I right-click on my data connection that I added and select Modify Connection. Then in the Modify Connection dialog I clicked Advanced... and then in the Advanced Properties dialog I changed Pooling from True to False. Now it works. Also, in the configuration file, the Enable SQL Server debugging must be checked. Also, I have to add cmd.CommandTimeout=1800 to the VB's sproc area else it will time-out while clicking thru the sproc in the debugger.

But, when not debugging, in order to get the app to run to completion without crashing with the error Error while executing 'a batch cmd' at line 0 , I have to uncheck Enable SQL Server debugging and set Pooling back to True. --Because not pooling the connections hurts performance.

In the Save DTS Package dialog
- in the Location field select Structured Storage
- in the File Name field set destination path of saved file
Press OK button

Server 2000: Query Analyzer Tips & Tricks

2007-06-20T12:33:00.004-05:00

You probably know that SQL Server stores metadata about all of the objects in a database. The system tables contain a wealth of information about column names, data types, identity seeds, and so on. But did you know that you can get that information with a single keystroke via Query Analyzer? Highlight the object name in any SQL statement and press Alt+F1. Figure 1 shows the results for a SQL Server table. If you don't have anything highlighted, Alt+F1 will give you information about the database itself. For an equally neat trick, highlight a SQL keyword and press Shift+F1; you'll go straight to the Books Online page that describes that keyword.

Getting .dll into Registry

2007-06-19T09:20:00.000-05:00

Download the file (MSRDO20.zip) to your desktop
Unzip the content of the file (a file called MSRDO20.DLL) to your desktop
Right now you should have a new file called MSRDO20.DLL that resides on your desktop
Copy this file to your Windows System Folder; this folder is usually found inside your 'C:\Windows' folder. It is called 'C:\Windows\System' or 'System32'...
Go to 'Start Menu' and choose 'Run'
A new window titled 'Run' will open; type the line 'regsvr32.exe msrdo20.dll' and hit 'Enter'.
A message will show up stating that the registration was successful.

Visual Studio Short-cuts

2007-06-08T23:12:00.001-05:00

Most of the time, you will Step Into or Step Over commands in your stored procedures. The commands below apply to a single T-SQL line:

Step Into (F11): Use to single step through your code. (Move the yellow arrow down one statement.)
Step Over (F10): Useful if you have lines of code that perhaps modify data or call other procedures that you don't care about while debugging. For example, you may want to skip code that performs auditing.
Step Out (SHIFT+F11): Execute the rest of the stored procedure without pause.
Run to Cursor (CTRL+F10): Position the cursor to a point in your code and then hit CTRL-F10 to execute all code up to that point.
Continue or Start Debug or Run (F5): Start Debug. Or resumes execution until completion or until the next breakpoint.
Toggle Bookmark (CTRL+K)
Help (F1)

When you provide a summary of the class using XML comments, your class displays documentation about itself in appropriate places within Visual Studio, such as in the List Members box. Open the List Members box by selecting Edit | Intellisense | List Members from the main menu bar or by clicking the Display an Object Member List icon on the Text Editor toolbar.

Getting Values

To see the value of your variable whilst in debug mode, use the "Command Window" (View >Other Windows >Command Window). Enter this: ? myVariableName
