Each line in the area under Quotation is a quotation pattern. A quotation pattern includes:

  • Left: a quotation character that is inserted before a value.

  • Right: a quotation character that is inserted after a value.

  • Escape: an escape method or character for the cases when the quotation character is part of a value. The <duplicate> value means that if a quotation character occurs within a value, it is doubled. You can specify your own escape character.

If there is more than one pattern, the first pattern is used.

UseApp general add,App general remove, App actions previous occurence and App actions next occurence to create, delete and reorder the patterns.

Quote values

Select when you want to enclose values within quotation characters.

  • Never: do not quote values.

  • When needed: quote a value if it contains the value or the row separator.

  • Always: quote all the values.

Table name, structure and data mappings



Target schema

Schema in which you want to create or to copy a table. You can select schemas in other data source.


Name of a new table or an existing table in case you want to add data to the existing table.


Comment to a table.

Columns | Keys | Indexes | Foreign Keys

Data mappings and definitions of columns, keys, and indexes. Double-click the line to start editing.

The Mapped to field specifies relation of a data column from the file and the corresponding column in the database. If you clear this field, no data is added to the target column in the database.

To remove a column, select the corresponding line and click the Remove button the Remove button.

Data and DDL previews



Data Preview

The generated preview of how your data will be imported to the database.

DDL Preview

A statement or statements that AppCode will run to create a table. You can edit the statements in the DDL preview field.

Encoding, errors, and logs




Select the character encoding for your data in the source file.

Write errors to file

Write errors that occur during the import in a text file.

Insert inconvertible values as null

Insert the NULL value into the table instead of the data that cannot be converted.

Disable indexes and triggers, lock table (may be faster)

Disable indexes and triggers during the import. Note that if you selected this option, it might lead to a situation when a trigger does not fire and fails to pass its results. Though it might improve the performance of the importing process. The option is available only when the target table (to which you copy values) has indexes or triggers.
