> Implement Quoting of identifiers
> --------------------------------
>
> Key: CAY-289
> URL: https://issues.apache.org/cayenne/browse/CAY-289
> Project: Cayenne
> Issue Type: Improvement
> Components: Cayenne Core Library
> Affects Versions: 1.2 [STABLE]
> Environment: Linux, Sun JDK1.5, MS SQL Server 2000, jtds-1.0, Croatian locale
> Reporter: Tomislav Nakic-Alfirevic
> Assignee: Andrus Adamchik
> Fix For: 3.0
>
>
> Say a table "t0" has an attribute "my attrib 0".
> You correct the obj-attribute to, for instance, "my_attrib_0", but the db-attribute is still "my attrib 0".
> When you try to run a query on "t0", the generated query looks like:
> SELECT ..., t0.my attrib 0, ... FROM dbo.t0 AS t0
> This, obviously, can't possibly work.
> The correct SQL would be:
> SELECT ..., t0.[my attrib 0], ... FROM dbo.[t0] AS t0
> Notice the square brackets arround the attributes and table names: that makes the string a valid attribute or table name valid.
> A further improvement might be to add the database name:
> SELECT ..., t0.[my attrib 0], ... FROM [dbname].dbo.[t0] AS t0
> I mention it because I use the quantum plugin as a database access plugin and it complained about a table called "dbo.tablename" (as I believe it should) and all was well when I used mydbname.dbo.tablename.
