I'm using a database trigger to save the stored procedure code after an alter.
I get the code using the EventData info.
My problem is that it's saving the code as plain text, so it's difficult to compare the code against other version of the procedure (all the code is in the same line).
Is there a way to save the code in a redeable format?
Thanks,
Andres
This may seem blatantly obvious and silly, but it is probably the best answer: Save both the old and the new text for the procedure. They should both be in the same format, and comparing them should be relatively easy.

Today I am being asked to format long SAS script with mainly Proc SQL which are not readable (do not respect simple SQL rules of readability):
imbricated SQL queries with no indentation
case is not respected
etc...
I tried automatic SaS formatter but it do not format Proc SQL. Do you have any ideas ? We have many scripts and the Team is ready to do that manually, it seems prone to error and I am not sure we'll have the same syntax at the end.
Any tips would be welcome!
I can add code snippets if needed but I think that the problem is clear and I am not the first to encounter it.
I would suggest ignoring the fact that you're in SAS for the moment, and instead focus on the SQL itself. Find a language you're comfortable with that has libraries that format code in other languages - Python for example can do this - and then:
Open the .sas file as a text file
Find "PROC SQL" text and grab from there to the "QUIT" (case insensitive)
Pass that inner text to the SQL code formatter
Grab the result and insert it back into the text file
Something along those lines is your best bet. SAS doesn't have anything built-in for this, so you're going to have to go outside here.
I am developing one automation tool for data migration from one table to other table, here I am looking for one function or SP for which I will pass source column and destination column as input parameter. I want output parameter to return true when source column data is compatible to copy to destination column. If not then it should return false.
For example, if a source column is varchar and a destination column is integer, the script should check all the data in a source column in good enough to move to an integer column or not and return the output flag. I want a script to work like this for all types of data types. Any suggestions will be helpful.
If you're on SQL Server 2012 you have TRY_CAST(), TRY_CONVERT() and TRY_PARSE() at your disposal (see this post by Biz Nigatu of blog.dbandbi for comparison).
That said, you still need to check for truncation errors, e.g. by converting to target datatype and back, then comparing the original value with the one after conversions.
I've seen similar tools in the past, might be a good idea to see if one isn't already available online for free. Even a purchase might be less expensive than the time you put into developing and troubleshooting your own tool.
I have an SSIS solution for this that I put together using EzAPI. I've got it posted to GitHub, so feel free to look:
https://github.com/thevinnie/SyncDatabases
Now, the part of that which is relevant to you would be where I use the information schema to make sure that the source and destination are schema matches. If not, C# script task will generate the statement to create, alter or drop the necessary column(s).
The EzAPI part is cool with SSIS because it will allow you to programatically generate an SSIS package. For the project requirements, I needed to be able to load data every time and not let schema changes in the source break the process.
Comments and recommendations are welcome. Hopefully it'll help, but I think you'll be looking at the INFORMATION_SCHEMA.COLUMNS either way.
I have to save a PDF-File into a BLOB-Column from a Oracle DB.
I can't use Java and have to use an INSERT-Statement.
The only solutions I've found while searching were very complex.
Is there an easy solution like: INSERT INTO (BLOB_COLUMN) VALUES(BLOBPDF("myPDF.pdf") or something like that?
I would suggest that you use a stored procedure in Oracle where you pass the path to your PDF file and calling the stored procedure does the insert.
Look at the last two sample example here.
If the load is "one-shot" you can use SQLDeveloper.
Otherwise you can use sqlloader (http://docs.oracle.com/cd/B19306_01/server.102/b14215/ldr_params.htm) that is designed for this type of operations
Within a stored procedure, I need to take a whole CSV file as a string, then pick out all the values in one "column" to do a further query on the database.
I cannot use a saved doc - so i think that rules out openrowset, and the whole thing has to be done within a stored procedure.
Have spent hours googling and trying, but can find a good answer. One possible was http://www.tainyan.com/articles/entry-32/converting-csv-to-sql-data-table-with-stored-procedure.html but it doesnt work and i can find the error.
How should this be done please?
I don't really like this but it will work, provided your csv column remains at the same column index. I'd be wary of the performance of this but it might work.
See Fiddle here: http://sqlfiddle.com/#!3/336b7/1
Basically convert your csv file to xml, cast to an xml type, then perform queries on the xml.
I'm using a DB2 database and I'm hoping for a query which will iterate over all stored procedures in a single database and print out the source code of each. No fancy formatting or performance requirements.
The reason for this (in case there's a better way of doing it) is I'm trying to track down usages of a particular table in our stored procs, so I want to be able to do a simple text search through all of them.
Also, I've got access to SQuirreL SQL client if anyone knows of a way via that.
Ah, figured it out. For other's reference:
select ROUTINENAME, TEXT from syscat.routines
where definer not in ('SYSIBM') AND ROUTINESCHEMA='databaseName'
I know this is old, but your answer started me on the right track. We are also using DB2, but don't have syscat.routines visible to us. However we do have SYSIBM.SYSROUTINES and that allows similar by doing
SELECT SCHEMA,
NAME,
TEXT
FROM SYSIBM.SYSROUTINES
WHERE SCHEMA = '<SCHEMA>'
and NAME = '<NAME>'
FOR FETCH ONLY WITH UR;
