sql server - "Cannot resolve collation conflict" even after fixing the collation -


the current database i'm using "primarydatabase" has collation "sql_latin1_general_cp1_ci_as", while "secondarydatabase" i'm trying access has collation "arabic_ci_as"

i changed collation secondarydatabase , set " sql_latin1_general_cp1_ci_as" , made sure has been changed in tables.

however, when run query below still collation conflict.

select * [myserver].[secondarydatabase].[dbo].[secondarytablename]  ltrim(rtrim([secondarytablename])) not in (select ltrim(rtrim(primaryfieldname))  primarytablename primaryfieldname2=1)

one way make query work use collate clause in order apply collation cast on both fields being involved in predicate of where clause:

select *  [myserver].[secondarydatabase].[dbo].[secondarytablename]  ltrim(rtrim([secondaryfieldname])) collate sql_latin1_general_cp1_ci_as       not in (select ltrim(rtrim(primaryfieldname)) collate sql_latin1_general_cp1_ci_as                primarytablename                primaryfieldname2 = 1)

the collate clause applied primaryfieldname might not necessary, since default collation of corresponding database (so primaryfieldname has collation).

another solution change collation @ field level, e.g.:

alter table secondarydatabase alter column secondaryfieldname varchar(50) collate sql_latin1_general_cp1_cs_as null
