bteqImport

Last updated: August 12, 2026

Loads data from a delimited file on the BTEQ execution host into a Teradata table. Generates the complete BTEQ import sequence (.IMPORT, .REPEAT, USING, and INSERT) so you do not need to hand-write the multi-command block in a <sql> element.

Getting the USING(...) clause wrong can silently corrupt data. This change type builds it from structured column definitions, reducing the risk of type mismatches.

Note: This change type does not support automatic rollback.

Available attributes

Attribute	Type	Required	Description
`file`	String	Yes	Absolute path to the input file on the BTEQ execution host. Must not contain newline characters.
`tableName`	String	Yes	Target table for the INSERT.
`schemaName`	String	No	Database or schema qualifier.
`format`	String	No	Import format. In `VARTEXT` mode, columns are read as delimited text, declared as `VARCHAR` in the `USING` clause, and non-`VARCHAR` types are cast in the generated `VALUES` clause. In `DATA` mode, columns use native types directly from a binary file produced by BTEQ `.EXPORT DATA`. Accepted values: `VARTEXT` or `DATA`. Default: `VARTEXT`.
`delimiter`	String	No	Field delimiter character. Applies to `VARTEXT` mode only. Default: `,`.
`repeatCount`	String	No	Number of rows to import. Use `` for all rows, or a positive integer to limit the import. Default: ``.

Column nested attributes

Each <pro-teradata:column> element defines a column in the import file and its target data type.

Attribute	Type	Required	Description
`name`	String	Yes	Column name. Must match a column in the target table.
`type`	String	Yes	Teradata data type. In `VARTEXT` mode, non-`VARCHAR` types (e.g., `INTEGER`, `DATE`) are declared as `VARCHAR` buffers in the `USING` clause and cast to this type in the generated `VALUES` clause. In `DATA` mode, the native type is used directly.
`format`	String	No	Date or timestamp format string for casting in `VARTEXT` mode (e.g., `YYYY-MM-DD`).
