Hi everyone, I've been playing with cast()s and such with this and can't seem to get things to work. I have a varchar string that's 18 characters long that I'd like to convert or cast to a decimal, with five decimal places. So for instance, this string: 00000001987600130 Would become 19876.00130 It's the case that I'll always have ...
I'm using PDO to extract data from Teradata, using an ODBC connect string. The query returns the correct number of rows but column 5 onwards is blank (as compared to using the same query with the PHP ODBC library) Column 5 happens to be a varchar(400) field and I've read that PDO had bugs in the past with varchar columns > 255 in lengt...

Here is my predicament. Basically, I need a column in a table to hold up an unknown length of characters. But I was curious if in Sql Server performance problems could arise using a VARCHAR(MAX) or NVARCHAR(MAX) in a column, such as: 'This time' I only need to store 3 characters and most of the time I only need to store 10 characters. B...
I have a database that uses codes. Each code can be anywhere from two characters to ten characters long. In MS SQL Server, is it better for performance to use char(10) for these codes and RTRIM them as they come in, or should I use varchar(10) and not have to worry about trimming the extra whitespace? I need to get rid of the whitespace...

This worked until the numbers incremented above 10000: Feedback.objects.filter(est__pk=est_id).aggregate(sid...

I've got a database with collation Danish_Norwegian_CS_AS and lots of varchar columns. I'd like to convert all this data to unicode, but haven't found a way to convert this data yet.

I have the following SQL statement which returns a single record as expected: select * from geodatasource_cities C, geodatasource_countries D where C.CC_FIPS = D.CC_FIPS and D.CC_ISO='AU' and UCASE(TRIM(C.FULL_NAME_ND)) LIKE '%JAN JUE%'; However, If I use the following SQL statement, no records are returned.

I cannot do select A...
I am trying to concatenate a list of IDs into a varchar(max) to pass into an openquery for a bulk update of data. My question is, is there an easy way to see if a string is beyond the length a varchar(max) can handle aside from comparing it to the number?
