PHP using SQL database to get field questions introduction to _php Tips

In the PB development process, because the database uses the ntext field, the following prompts the error, depressed for a long time can not find the solution, after consulting a large number of data, finally understand:
PB Error: You cannot use Db-library (such as ISQL) or ODBC 3.7 or earlier to send the ntext data or Unicode data that uses only Unicode collations to the client.
————————————————
Because the ntext and nvarchar fields in SQL Server store content in Unicode encoding, PHP will get the wrong time to read with ntext and nvarchar type fields through MSSQL extensions.

If the Title field type is nvarchar,content field type is ntext, the following SQL statement complains:
Select Title,content from article

The correct wording is:
Select CONVERT (varchar (255), title) as title, convert (text,content) as content from article
Or do not use the ntext field
This is very useful to solve my problems!
