AS400 Queries

AS400 Queries

Certified

Execute multiple SQL statements against IBM AS/400 (iSeries)

Runs multiple SQL statements separated by semicolons, either sequentially or within a transaction. Supports parameterized queries and all fetch modes. Set transaction to false to disable transactional behavior (default is true). Default fetchSize is 10,000 rows for STORE mode. Based on DB2 implementation.

yaml
type: io.kestra.plugin.jdbc.as400.Queries

Send a SQL query to a AS400 Database and fetch a row as output.

Properties

SQL statement(s) to execute

Runs one or more SQL statements rendered with flow variables. Query tasks accept a single statement; Queries tasks can execute multiple statements separated by semicolons

The JDBC URL to connect to the database

SQL to execute after main query in same transaction

Optional SQL executed in the same transaction after the main statement. Useful for marking rows as processed to avoid duplicates; only a single statement is allowed. Commit covers both sql and afterSQL

Assets this task consumes as inputs or produces as outputs, for lineage tracking and the asset graph (Enterprise Edition). A flow declaring this property on a task is rejected in the open-source edition.

Definitions
assetFailureBehaviorstring
Possible Values
IGNOREFAILWARN

Asset failure behavior

Behavior applied to the task state when a declared asset fails to render, emit, or be persisted (e.g. a lock conflict): FAIL escalates it to FAILED, WARN (default) warns it if it would otherwise succeed, IGNORE leaves the state untouched.

enableAutobooleanstring

Whether to auto-register assets referenced dynamically at runtime that are not statically declared in inputs or outputs.

The assets consumed as inputs.

Defaultfalse

Compute per-column statistics of the fetched rows

When true, writes an ION file with one entry per column (column, jdbcType, nulls, distinct (approximate), min, max, mean, median, minLen, maxLen) and exposes its URI in the columnStats output. Statistics are computed while the rows are read, without running a second query. Only applies to fetchType FETCH and STORE; LOB, binary and array columns are skipped. min and max are omitted for string columns longer than 256 characters, and median is computed on a bounded sample of the values

Default100000

Number of rows used to compute column statistics

Only used when columnStats is true. Statistics stop at this many rows while all rows are still fetched or stored. Must be at least 1. Default: 100,000

Default10000

Number of rows to fetch per database round trip

Controls JDBC fetch size for STORE mode. Default: 10,000 rows; use Integer.MIN_VALUE for MySQL streaming. Ignored for FETCH and FETCH_ONE

DefaultNONE
Possible Values
STOREFETCHFETCH_ONENONE

Result fetching mode

FETCH returns all rows, FETCH_ONE returns the first row only, STORE streams rows to internal storage (ION), NONE returns no data. Default: NONE

SubTypestring

Output file names to capture after SQL execution

Creates named temporary files in the task working directory before the SQL runs, making their absolute paths available as {{ outputFiles.name }} Pebble variables in the SQL template. Only supported by embedded, in-process drivers (DuckDB, SQLite) where the database engine writes to the same filesystem as the Kestra worker. Remote database drivers (Postgres, MySQL, etc.) do not support this — they execute SQL on a separate server that cannot write to the Kestra worker filesystem.

Defaultfalse

Expose the executed SQL statement in the outputs

When true, the rendered SQL is exposed in the statement output, with the values of the secret() calls used in sql replaced by *** and truncated to 64 KiB. Disabled by default so that SQL text never leaks into outputs unless requested

Named parameter bindings for SQL query

Map of parameter names to values, bound to : name placeholders as prepared-statement parameters; supports nulls and typed values. Colons in literals, quoted identifiers, comments and :: casts are left as is; a : name missing from this map is bound to NULL with a warning.

The database user's password

The time zone id to use for date/time manipulation. Default value is the worker's default time zone id

Defaulttrue

Transaction

If one query failed, rollback transactions.

The database user

SubTypeinteger

The number of affected rows for each query that doesn't return a result set

One entry per INSERT, UPDATE, DELETE or DDL statement, in execution order, as reported by the JDBC driver (DDL statements usually report 0). Queries returning a result set are not included here; their results are in outputs.

Total size of the stored result files in bytes

Only populated when fetchType is STORE

Formaturi

URI of the column statistics file in internal storage

Only populated when columnStats is true and fetchType is FETCH or STORE; columns of all result sets are merged by name

Total execution duration in milliseconds

Includes reading the result rows of every statement

The list of per-query outputs

Definitions

statementstring

Executed SQL statement

Only populated when outputStatement is true. Values of secret() calls are replaced by *** and the text is truncated to 64 KiB

tablesarray

Tables read or written by the statement

One of READ, WRITE, CREATE or DROP.

confidencestring
Possible Values
MEDIUMLOW

uristring
Formaturi

URI of stored results in internal storage

warningsinteger

Formaturi

URI of the per-statement details file in internal storage

ION file with one {index, kind, rowsAffected, durationMs} entry per executed statement

Tables read or written by the statements

Detected from the SQL text, so this is a best effort: CTEs, temporary tables and dialect specific syntax can lower the confidence or be missed. Limited to 50 entries, see tablesTruncated
