Обсуждение: Insert path fails

Hello-

I am running PostgreSQL 7.2.1 on i386-portbld-freebsd4.6.  I'm connecting
from a program on windows nt 4.0, using the 7.02.00.05 ver. of PGSQL-ODBC
drivers.

When I try to insert a windows UNC path:

\\RAID\Raid\control tiffs\50_gray.tif


into the database, I end up with this:

\RAIDRaidcontrol tiffs(_gray.tif




Here is the relevent stuff from the psqlodbc file:

conn=215355400, query='Insert Into
Images(OrderID,Roll,Frame,ImageType,Path,Category,Sequence,Gamma,Width,
Length,Filetype,PreviewWidth,PreviewLength,CropX,CropY,CropWidth,CropLength)
Values('me','control tiffs','50_gray',0,'\\RAID\Raid\control tiffs\50_gray.tif'
,'All',0,1.0,2000,2500,'TIFF',400,500,50.0,50.0,100.0,100.0)'





Why does this insert the wrong value into the database?


Thanks

-Steve

It's a spec of PostgreSQL.
The ODBC driver passes the query as is.

The backslash is an escape character in PostgreSQL,
and is stripped off at parsing time.  Your
alternatives are:
* Double every backslash you want to preserve, i.e.
\\\\RAID\\Raid\\control tiffs\\50_gray.tif
* Add extra quotes (a mess, don't even try it)
* Use the quote_literal() function, which causes
PostgreSQL to accept the text as-is: e.g.
INSERT INTO <table> (<field>) VALUES
quote_literal('text goes here')
