Sandeep KumarWhile working on multi-language support we need to insert different language data in the same field or different fields of a SQL Server table.
There are two basic rules one needs to keep in mind while storing multi-lingual or Unicode data:
- First, the column must be of Unicode data type (i.e.,
nchar,nvarchar,ntext). - And second is that the value must be prefixed with N while insertion.
Below is the sample script with output to understand it better.
In the output, you can see that values in Var_Field are saved as ????, even though in script N is prefixed while inserting. This is because the field is of VARCHAR type.
| Id | Var_Field | NVar_Field |
|---|---|---|
| 1 | ?? ?? ???? ?? | यह एक शब्द है |
| 1 | ?? ??? ???? ?? ????? ?? | ਇਹ ਇੱਕ ਸ਼ਬਦ ਦਾ ਹੁੰਦਾ ਹੈ |
Note:
If you are using a stored procedure to insert the Unicode data, then make sure that N is used before the string while passing the parameter to the stored procedure. Also, make sure the parameter declared in the stored procedure is of Unicode type.
