View 5 Repliesim learning t-sql, infact i needed its while-loop to loop through records of a table, i found this code in some book:
[Code]....
i understand here that setting the rowcount variable to 1 will force the select statements to return only one record, do all above select statements return one record only?
if the underlined select statement returns one record everytime it is executed, isn't it supposed to return the same first record of the table everytime? is there a better way to loop through a table's records?

View 3 RepliesI have to retreive all records from a table except 1 record. For example: I give example from default database in SQL ie "master" In "master" DB we have "spt_values" table. Now if I want to retreive all records from spt_values table except 1-1 record of type = A and type = B. To retreive all records its a simple query "Select * from spt_values where type in ('A','B')" -- this will returns 16 records. Now I want to retreive all record except 1-1 record left in each type, so it will return 14 records in result.

i need to create 2 temporary tables.The records inserted into the 2nd table is the same as that from table1.
Now, i am inserting some other records into table 2.what i need is, to retrieve the count of the recently added records into table2.How to achieve this?
I have a table with a structure and records as follows,
Record ID Applied From To
01 01/01/2010 01/01/2010 10/01/2010
02 12/03/2010 13/03/2010 15/03/2010
03 21/05/2010 22/05/2010 12/06/2010
I have a stored procedure which must be provided with a requested FROM date and TO date. If a given FROM date and TO date is in between any record set available in the table, it must return an error. For example,
According to above table, there is a request FROM 01/01/2010 TO 10/01/2010, and If the user enters 06/01/2010 as FROM date [Requested FROM date is already in between the Record ID 01 - FROM date and TO Date] , thus, it must display an error, or print a message.
Why do I get this nasty error? I have taken a table, and I have made an exact copy to another table. The new table hold the purged records from the other table. I want the records out of my other table to speed up the site. I don't want records from banned sites cluttering up the table.
So my procedure has gotten the thing to write the row to the table, but I get an error about a conversion to an integer. What could this be referring to?

I've got a sp as below:
The functionality I want to achieve is that when isHomePageFeatured is checked then this record is set to 1 for that column and for all the other records in the table it is set to 0.
This is fine for update as I can use the property Id to compare against, but for the newly inserted record it doesn't yet have a propertyId so I wondered if using newID() to affect all other records would have the same affect.

But this is not secured because anybody can look up any students result if you have the number which is even written on their school uniform for identification.
I have being trying to secure this result by trying to generate or code special numbers that the students will input with their school number. The special numbers will be random numbers and may be from 10 and above, it might even contain letters. How do
I code this. I believe this is the best asp.net forum. I want the students to be inputing this special unique numbers and their student numbers so that there result will be avaliable to them.

I have two tables for storing language translations - tblEN and tblES. They have the same structure which is nvcEnglish and nvcLocal - both nVarChar fields.
In nvcLocal of the Spanish table, I enter the Spanish translations of words and phrases used within my app. Problem is, when I add a bunch of new records to the English table I also have to go in and repeat the data entry into the Spanish table. I am wondering if there is a way to import the newly added records into the Spanish table using Transact SQL?The plain language query would be something like:
If the data in tblEN.nvcEnglish does not exist in tblES.nvcEnglish then insert a new row into tblES with the values from tblEN

I have a gridview, and I set the datasource in page_load to a linq query. I have delete linkbutton in the grid and am writing code in gridview1_rowdeleting event to delete the record from the table and all its records in child tables. Works fine, except when I databind() after the deletes to refresh the grid, it thinks there are no records left in the table and goes to the <emptytemplate> . There are in fact many other records that should appear. When I go out of the gridview and come back in, everything is fine. The proper records have all been deleted, and the remaining ones show. Here is the code. the table being displayed is Schedule. It has child records in the two other tables.
