File Extract
Settings
Connection | Select a connection of the above mentioned type | ||||
SQL query (optional) |
By entering an optional SQL statement in the extract, the data can be sorted in advance. Use the name of the extract's connection as the table name in the SQL statement. If no SQL query is entered, performance is improved and all columns and all lines are extracted from the file. Table names and field names must be written in double quotation marks in the query statement. The columns are identified with the standard aliases of the extract. Two cases are distinguished for these aliases:
The SQL syntax of the H2 database engine is used. For more information see http://www.h2database.com/html/grammar.html. |

Field structure |
The resulting field structure of the File extract can be generated with the Refresh button. The number and the (original) name of all columns are displayed. For each column you can optionally define the following settings with double-click:
|
||||
Skip lines | Ignores a specific number of rows at the beginning of the file. If the header row is set, only the subsequent rows after the header are ignored. The default value of the Skip lines is 0. | ||||
Start | Defines the first line number to be read from the file. If the header row is set, only the subsequent rows after the header are ignored. The default value of the Start is 1. | ||||
End |
Defines the last line number to be read from the file. The default value of the End is 1, meaning all rows are read. |
||||
Columns |
Limits the maximum number of columns to be read. If not set, all columns that are presented in the first data row are used. |
