Bulk loading data using the LOAD TABLE statement

•DATE, TIME, DATETIME or TIMESTAMP string as ASCII characters. You must define the input-date-formator input-datetime-formatof the string using one of the corresponding formats for the date and datetime data types supported by Adaptive Server IQ. For information about these, see the Adaptive Server IQ Reference Manual.

Note The column-specis for IQ tables only. If you specify a column-specfor a Catalog Store table, you get an error.

The NULL portion of the column-specindicates how to treat certain input values as NULL values when loading into the table column. These characters can include BLANKS, ZEROS, or any other list of literals you define. When you specify a NULL value or read a NULL value from the source file, the destination column must be able to contain NULLs.

The FILLER clause indicates you want to skip over a specified field in the source input file. For example, there may be characters at the end of rows or even entire fields in the input files that you do not want to add to the table. As with the column-specdefinition, FILLER allows you to specify ASCII fixed length of bytes, variable length characters delimited by a separator, and binary fields using PREFIX bytes. FILLER clause syntax is as follows:

FILLER ( filler-type ) filler-type:

{input-width PREFIX { 1 2 4 } ’delimiter-string’ }

For more information on how to use data conversion options, see “Converting data on insertion”.

Specifying files to load You specify one or more files from which to load data. In the FROM clause, you specify each filename-string, and separate multiple strings by commas.

The files are read one at a time, and processed in a left-to-right order as specified in the FROM clause. Any SKIP or LIMIT value only applies in the beginning of the load, not for each file.

If a load cannot complete, for example due to insufficient memory, the entire load transaction is rolled back.

filename-stringThe filename-stringis passed to the server as a string. The string is therefore subject to the same formatting requirements as other SQL strings. In particular:
