SVL_STATEMENTTEXT
Use the SVL_STATEMENTTEXT view to get a complete record of all of the SQL commands that have been run on the system.
The SVL_STATEMENTTEXT view contains the union of all of the rows in the STL_DDLTEXT, STL_QUERYTEXT, and STL_UTILITYTEXT tables. This view also includes a join to the STL_QUERY table.
SVL_STATEMENTTEXT is visible to all users. Superusers can see all rows; regular users can see only their own data. For more information, see Visibility of Data in System Tables and Views.
Table Columns
| Column Name | Data Type | Description |
|---|---|---|
| userid | integer | ID of user who generated entry. |
| xid | bigint | Transaction ID associated with the statement. |
| pid | integer | Process ID for the statement. |
| label | character(30) | Either the name of the file used to run the query or a label defined with a SET QUERY_GROUP command. If the query is not file-based or the QUERY_GROUP parameter is not set, this field is blank. |
| starttime | timestamp | Exact time when the statement started executing,
with 6 digits of precision for fractional seconds. For example:
2009-06-12 11:29:19.131358
|
| endtime | timestamp | Exact time when the statement finished executing,
with 6 digits of precision for fractional seconds. For example:
2009-06-12 11:29:19.193640
|
| sequence | integer | When a single statement contains more than 200 characters, additional rows are logged for that statement. Sequence 0 is the first row, 1 is the second, and so on. |
| type | varchar(10) | Type of SQL statement:
QUERY, DDL, or
UTILITY.
|
| text | character(200) | SQL text, in 200-character increments. This field might contain special characters
such as backslash (\\) and newline (\n).

Sample Query
The following query returns DDL statements that were run on June 16th, 2009:
select starttime, type, rtrim(text) from svl_statementtext where starttime like '2009-06-16%' and type='DDL' order by starttime asc; starttime | type | rtrim ---------------------------|------|-------------------------------- 2009-06-16 10:36:50.625097 | DDL | create table ddltest(c1 int); 2009-06-16 15:02:16.006341 | DDL | drop view alltickitjoin; 2009-06-16 15:02:23.65285 | DDL | drop table sales; 2009-06-16 15:02:24.548928 | DDL | drop table listing; 2009-06-16 15:02:25.536655 | DDL | drop table event; ...
Reconstructing Stored SQL
To reconstruct the SQL stored in the text column of SVL_STATEMENTTEXT,
run a SELECT statement to create SQL from 1 or more parts in the
text column. Before running the reconstructed SQL, replace
any (\n) special characters with a new line. The result of the
following SELECT statement is rows of reconstructed SQL in the query_statement field.
select LISTAGG(CASE WHEN LEN(RTRIM(text)) = 0 THEN text ELSE RTRIM(text) END, '') within group (order by sequence) AS query_statement from SVL_STATEMENTTEXT where pid=pg_backend_pid();
For example, the following query selects 3 columns. The query itself is longer than 200 characters and is stored in parts in SVL_STATEMENTTEXT.
select 1 AS a0123456789012345678901234567890123456789012345678901234567890, 2 AS b0123456789012345678901234567890123456789012345678901234567890, 3 AS b012345678901234567890123456789012345678901234 FROM stl_querytext;
In this example, the query is stored in 2 parts (rows) in the text column of SVL_STATEMENTTEXT.
select sequence, text from SVL_STATEMENTTEXT where pid = pg_backend_pid() order by starttime, sequence;
sequence | text ----------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 0 | select\n1 AS a0123456789012345678901234567890123456789012345678901234567890,\n2 AS b0123456789012345678901234567890123456789012345678901234567890,\n3 AS b012345678901234567890123456789012345678901234 1 | \nFROM stl_querytext;
To reconstruct the SQL stored in STL_STATEMENTTEXT, run the following SQL.
select LISTAGG(CASE WHEN LEN(RTRIM(text)) = 0 THEN text ELSE RTRIM(text) END, '') within group (order by sequence) AS text from SVL_STATEMENTTEXT where pid=pg_backend_pid();
To use the resulting reconstructed SQL in your client, replace any (\n) special characters with a
new line.
text ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ select\n1 AS a0123456789012345678901234567890123456789012345678901234567890,\n2 AS b0123456789012345678901234567890123456789012345678901234567890,\n3 AS b012345678901234567890123456789012345678901234\nFROM stl_querytext;
