About

This how-to shows you how to generate an string,varchar, text sequence with the column sequence generator.

To generate data, you need to create a generator file that will describe the data to be generated.

The below data resource generator:

  • has the name sequence_varchar–datagen.yml
  • has the logical name sequence_varchar
  • will generate 30 values (MaxRecordCount count)
  • has a column named id that has sequence data generator that:
    • starts by default at the value 1
    • increments by default with the value 1
  • has a column named seq_char with the varchar data type that has sequence data generator
MaxRecordCount: 30
Columns:
  - name: id
    type: integer
    comment: A id column to see easily the number of values generated
    DataGenerator:
      type: sequence
  - name: seq_char
    type: varchar
    precision: 2
    comment: A column with a sequence character generator
    DataGenerator:
      type: sequence
