Advanced Usage
Multiple SQL Statements
Lineage result combined for multiple SQL statements, with intermediate tables identified
$ sqllineage -e "insert into db1.table1 select * from db2.table2; insert into db3.table3 select * from db1.table1;"
Statements(#): 2
Source Tables:
db2.table2
Target Tables:
db3.table3
Intermediate Tables:
db1.table1
Verbose Lineage Result
And if you want to see lineage result for every SQL statement, just toggle verbose option
$ sqllineage -v -e "insert into db1.table1 select * from db2.table2; insert into db3.table3 select * from db1.table1;"
Statement #1: insert into db1.table1 select * from db2.table2;
table read: [Table: db2.table2]
table write: [Table: db1.table1]
table cte: []
table rename: []
table drop: []
Statement #2: insert into db3.table3 select * from db1.table1;
table read: [Table: db1.table1]
table write: [Table: db3.table3]
table cte: []
table rename: []
table drop: []

Summary:
Statements(#): 2

Column-Level Lineage
We also support column level lineage in command line interface, set level option to column, all column lineage path will be printed.
INSERT OVERWRITE TABLE foo
SELECT a.col1,
b.col1 AS col2,
c.col3_sum AS col3,
col4,
d.*
FROM bar a
JOIN baz b
ON a.id = b.bar_id
LEFT JOIN (SELECT bar_id, sum(col3) AS col3_sum
FROM qux
GROUP BY bar_id) c
ON a.id = sq.bar_id
CROSS JOIN quux d;
INSERT OVERWRITE TABLE corge
SELECT a.col1,
a.col2 + b.col2 AS col2
FROM foo a
LEFT JOIN grault b
ON a.col1 = b.col1;
Suppose this sql is stored in a file called foo.sql
$ sqllineage -f foo.sql -l column
<default>.corge.col1 <- <default>.foo.col1 <- <default>.bar.col1
<default>.corge.col2 <- <default>.foo.col2 <- <default>.baz.col1
<default>.corge.col2 <- <default>.grault.col2
<default>.foo.* <- <default>.quux.*
<default>.foo.col3 <- c.col3_sum <- <default>.qux.col3
<default>.foo.col4 <- col4
Lineage Visualization
One more cool feature, if you want a graph visualization for the lineage result, toggle graph-visualization option
Still using the above SQL file:
sqllineage -g -f foo.sql
A webserver will be started, showing DAG representation of the lineage result in browser.
