Hi,
Am trying to convert tsv file to table for performance analysis, but am unable to do that:angry:
have tried
1. Converting TSV - to Excel- and then importing to table
this worked but truncated few columns (more than 25 columns!!)
2. Imported TSV directly to table -- encountered error
3. Coverted TSV - to CSV - to table -- same error
4. Converted TSV- to TXT - to table -- same error
5. Converted TSV- toTXT- to EXCEL - to table - same error
now other option which i think will work is creating a table of similar columns manually and then copy it from excel to table..but its gonna be time consuming and will crash down my machine!!
Can any one please help me in this.
Thanks
Shree

the error is related to the row size of the insert; > 8062

for example, if i have 25 columns, and they are all defined as varchar(500), 25 X 500 = 12500, which is bigger thant he allowed 8062 chars for an update.

if you change the destination table to be varchar(max) for most of the columns , i believe it will work.

Create the table first and then use BULK INSERT.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

hi again,

Though am able to convert tsv to table now..but was wondering why did it truncated the columns when i converted tsv- to excel -to table?

Total number of columns were 373 but after import they were just 256 i.e. 117 columns missing..(sry i had said more than 25 in earlier post, i should have been more specific on that) and total number of rows are 8461.

Can any one help me in understanding this.

Thanks

Shree

The maximum number of columns in an in pre-Excel 2007 worksheets is 256.

"The Excel 2007 "Big Grid" increases the maximum number of rows per worksheet from 65,536 to over 1 million, and the number of columns from 256 (IV) to 16,384 (XFD)."
