I am linked to a Proficy Historian that allows periods in the column names. Because the data is stored in a non DBMS format I can not use openquery
to get the data because there is no set schema to the tables. So I must use four part name syntax to get the data. This example works:
SELECT * FROM iHist...[SELECT * FROM ihTrend]
but this fails with Incorrect syntax near '.'.
SELECT * FROM iHist...[SELECT [SERVER.pid_astatus[07][0].F_CV.Value] FROM ihTrend]
where SERVER.pid_astatus[07][0].F_CV.Value
is the name of the column
This fails as well with Incorrect syntax near the keyword 'from'.
SELECT * FROM
iHist...[SELECT [SERVER.pid_astatus[[07]][[0]].F_CV.Value] from ihTrend]`
Any ideas on how I can make SQL Server see this as a column?
EDIT:
Martins suggestion of the right brackets to escape the brackets work only on the outside of the sql call
SELECT [SERVER.pid_astatus[07]][0]].F_CV.Value] FROM iHist...[SELECT * FROM ihTrend]
However it does not work inside Incorrect syntax near the keyword 'from'.
SELECT * FROM iHist...[SELECT [SERVER.pid_astatus[07]][0]].F_CV.Value] FROM ihTrend]
EDIT
SELECT * FROM iHist...[SELECT [SERVER.pid_astatus[07]][0]].F_CV.Value]] FROM ihTrend]
I had to escape the column escape :)
You only need to escape these ]
[pid_astatus[07]][0]].F_CV.Value]
This works for me
CREATE TABLE #t(
[pid_astatus[07]][0]].F_CV.Value] int
)
SELECT [pid_astatus[07]][0]].F_CV.Value]
FROM #t
(Edited to reflect new knowledge, if you like this vote for Martin Smith's answer instead!)
Escape the ]
by doubling them:
SELECT * FROM
iHist...[SELECT [SERVER.pid_astatus[07]][0]].F_CV.Value] from ihTrend]
Based on your comment, try:
SELECT [SERVER.pid_astatus[07]][0]].F_CV.Value] FROM iHist...ihTrend
