在 SSIS 中将 VARCHAR(MAX) 字段从 SQL 导出到 Excel

Question

I'm creating a SSIS Package to export Data from a SQL Server Table into an Excel Sheet. My Table has one column of datatype VARCHAR(MAX) . And this column can have data as big as 30,000 characters sometimes. So I used a Data Conversion block to convert that column's DataType from it's original datatype text stream [DT_TEXT] to Unicode text stream [DT_NTEXT] . But when I execute the Package, I get this error An error occurred while setting up a binding for the "MyColumnName" column. The binding status was "DT_NTEXT" .

I googled a lot but I couldn't get an answer to my problem. I'd appreciate all the help that I could get.

Answer 1

You can skip the data conversion task and just force the type when you extract from SQL Server SELECT CAST(MyBigColumn AS nvarchar(max)) As MyBigColumnUnicode but you're going to run into the problem that a cell in Excel cannot hold 100k characters.

Total number of characters that a cell can contain: 32,776
