DB2 export command exports data selected by SQL statement from a table or view to an external files in the format of del, asc ascii formatwsf, ixf etc. The DEL format uses delimiter and column separator and decimal point. The default string delimiter is double quote " and column separator is commaand Decimal Point is dot.

It is a generic relational database exchange format which supports an end-of-record delimiter. IXF architecture supports to exchange of relational database structures and data.

IXF is used for transferring data across platforms. The following examples illustrates the use of Export command. Example 1 : Export all rows in the Employee table to the file emp.

To connect to some of these data sources, you may have to download and install additional files.

For info about how to connect to a data source that's not listed here, see The Connection Strings Reference. This third-party site contains sample connection strings and more info about data providers and the connection info they require.

If you already work with your data source and destination, you probably already have the permissions that you need. Tap the F1 key from any page or dialog box of the wizard to see documentation for the current page. The pages of the wizard use some of the language of SSIS. In SSIS, the basic unit is the package. The wizard creates an SSIS package in memory as you move through the pages of the wizard and specify options.

Later you can reuse the package and extend it by using SSIS Designer to add tasks, transformations, and event-driven logic. Start the wizard. Skip to main content. Contents Exit focus mode. What happens when I run the wizard? See the list of steps. There's also a separate page of documentation for each page of the wizard.

What sources and destinations can I use? Data source Do I have to download additional files? To connect to an enterprise database, you typically have to have two things: 1. Client software. If you already have the client software installed for your enterprise database system, then you typically have what you need to make a connection.

If you don't have the client software installed, ask the database administrator how to install a licensed copy. Drivers or providers. Microsoft installs drivers and providers to connect to Oracle. Text files flat files No additional files required.

Just like normal insert operations, DB2 validates the data and checks against the table definitions, constraints such as referential integrity and check constraintsand index definitions.

Triggers with satisfying conditions are also activated. The utility supports options and import modes that let you customize its behavior. The syntax diagram of the import command is very long; Figure Please refer to the DB2 Command Reference for the complete syntax diagram.

Although the syntax diagram may seem complex, it is quite easy to understand and follow. Let's start with a simple import command and discuss the mandatory options. To a certain degree, the import command is structured much like the export command: you have to specify the input file name, format of the file, and the target table name.

For example:. This command takes the file employee. We also recommend you to specify the optional clause messages to save the errors and warning messages and the import status. In section The previous example uses insert to indicate that new data is to be appended to the existing employee table.

Table Import Modes Mode. Adds the imported data to the table without changing the existing table data. The target table must already exist. Adds the imported data to the target table or updates existing rows with matching primary keys. The target table must already exist with primary keys. Creates the table, index definitions, and row contents. The input file must use the IXF format because this is the only format that stores table and index definitions.

Deletes all existing data from the table and inserts the imported data. The table definition and index definitions are not changed. If the table exists, this option behaves like the replace option.

If the table does not exist, this option behaves like the create option, which creates the table and index definitions and then inserts the row contents. This option requires the input file to be in IXF format.

In Figure The warningcount option indicates that the utility will stop after 10 warnings are received.Experts Exchange always has the answer, or at the least points me in the correct direction!

Last Modified: I'm trying to load a colon-delimited text file into a db2 table and I need to know the best method for doing this. Should I use the import utility or the load utility? Also, I am unsure if the syntax for either of these tools. How do I specify the delimiter? Can anyone help me with this? Thanks in Advance.

Start Free Trial. View Solution Only. Commented: If its a huge ammount of data then Load might be the right choice otherwise Import will do fine I'd imagine. From IBM DB2 Help: The load utility is capable of efficiently moving large quantities of data into newly created tables, or into tables that already contain data.

The load utility does not fire triggers, and does not perform referential or table constraints checking other than validating the uniqueness of the indexes.The export utility extracts data from a table into a file.

Figure As you can see, the command supports many different options. Let's start with a simple export command and discuss how to use the options to customize the command. The following example of the export command exports all the rows in the employee table to the file empdata. All the keywords in this command are mandatory, that is, you have to provide the output file name, specify the file format, and the SELECT statement that will retrieve the rows to be exported.

Using the optional messages clause you can specify a file name where warning and error messages of the export operation are logged. If no message file accompanies the messages clause, the messages are written to standard output.

Though optional, we highly recommend you use this clause so that all the messages generated by the utility are saved. Thus, if you want to export data from two tables, they can be joined as shown in the following example:. The above example joins the employee and department tables to obtain information for each department manager. If the command is successfully executed, the number of rows exported is returned :. When the command finishes successfully with no warning or error message, the message file deptmgr.

The export utility exports data to a file using default file formats. For example, as mentioned earlier, if you are exporting a table to a file in DEL format, the default column delimiter is a comma, and the default string delimiter is the double quote. What happens if the table data to be exported contains these delimiters as part of the data?

The file exported may contain data that can be confused as a delimiter, making it impossible for an import or load operation to work correctly. To customize the export file format to use different delimiters, use the modified by clause. The following sections introduce some of the most common file type modifiers.

To use a different column delimiter other than the comma, specify the coldel file type modifier in the modified by clause. The following example specifies to use a semicolon as the column modifier. Note that there is no space between the keyword coldel and the semicolon. You can enclose character strings with a different delimiter by using the keyword chardel. Continuing with the previous example, the character delimiter used here is a pair of single quote. You can also export data in a specific date format you prefer by using the timestampformat modifier.

In many cases, the code page of the target database server is not the same as the source server. To ensure data is handled correctly in the target server, you should pay attention to the code page of the exported data. By default, data exported is in the same code page as the application for which the export command is invoked.

With the export utility, you can use the codepage modifier to convert character data from the application. Note that this modifier cannot be used with the lobinsfile modifier, which is discussed in the next section. Due to these sizes, the export utility by default extracts only the first 32KB of data of the LOB values in the export file.

To extract the entire LOB, you must use the lobsinfile modifier. All the LOB values for a particular LOB column are stored in a single file that is separate from the regular export data file. The format of the LLS is. For example, the following export command generates three files.
