![]() =REPT('z', 4000), which will create a string of 4000 of the letter 'z'. One way of doing this is using the REPT() function, e.g. You must make sure that the column in at least one of the sampled rows contains a value longer than 255 characters.So to import data from a column that contains rows with large amounts of data without truncation, there are two options: If on the column it doesn't notice anything too large, it will default to a 255 character text column. If so, the problem is probably that SSIS samples some number of rows at the beginning of your spreadsheet when it creates the Excel source. Not fun to set up but once done it is reliable.I assume you're trying to import this using an Excel Source in the SSIS dialog? If you have to load multiple csvs from a single folder with this method, they all must use the same Schema.ini file but this file can include separate schemas for each csv filename. The text within the Schema.ini file should look something like this: Set data access mode to "SQL command" and set the SQL command text to "SELECT * FROM myexportname.csv" or whatever the name of the csv file is. In Connection Managers I chose "New OLE DB Connection", New Provider: Microsoft Jet 4.0 OLE DB Provider.Ĭlicked "All" in left pane and set Extended Properties to the following (without the quotes): "text HDR=Yes FMT=Delimited"Ĭlicked "Connection" in the left pane and set Database file name to the folder where the csv is (without including the csv filename).Ĭreated an OLE DB Source in the Data Flow and pick the new connection manager in the first dropdown. I got around it by saving from Excel in csv format, then putting a Schema.ini file in the same folder as the csv, and specifying the data types of each column (Memo for long strings, or Text, Date, Double etc) within the Schema.ini file. A real pain as Microsoft were not handling embedded delimiters well in SSIS at the time. I had a similar issue in SSIS 2008 with an Excel file that had columns wider than 255 characters, as well as embedded text qualifiers and delimiters. ![]()
