When I use the following query:
create table #name;
I get the following error:
SQL Error [42601]: ERROR: syntax error at end of input
I am doing this in RedShift DB
I also tried
"create temporary table #name;" and "create temporary table name;".
I am getting the same error for this query also.
I am trying to create a temporary table here, but I keep getting syntax error
use the CREATE TEMPORARY TABLE statement.
CREATE TEMPORARY TABLE #name (
id INTEGER,
name VARCHAR(255)
);
https://docs.aws.amazon.com/redshift/latest/dg/r_CREATE_TABLE_NEW.html
You must provide the table and columns name, as well as the data types that will be used in it.
For Eg :
create table table_name (
column_name data_type,
column_name data_type
);
If you specify a table name that begins with '# ', the table is created as a temporary table.
create table #name (
id INTEGER,
name VARCHAR(255)
);

I am trying to create a Hive table with partitions but getting the above error. What am I doing wrong?
CREATE TABLE IF NOT EXISTS schema.table_name
(
ID varchar(20),
name varchar(50)
)
PARTITIONED BY (part_dt varchar(8), system varchar(5));
The code works without the partitioning clause. Something gives up during partitioning.
Statement is working in hive. Pls find below screenshot.
Its possible that some of column names are reserved keywords and that is throwing error. if yes, you can use below SQL too.
CREATE TABLE IF NOT EXISTS schema.table_name
(
`ID` varchar(20),
`name` varchar(50)
)
PARTITIONED BY (`part_dt` varchar(8), `system` varchar(5));
I am trying to change the column size from 100 to 150 varchar data type using following query:
alter table data_warehouse.tbl_abc
alter column first_nm varchar(150) null;
Getting the following error:
SQL Error [42601]: ERROR: syntax error at or near "varchar"
Position: 77
The syntax is a bit different, so try this:
ALTER TABLE data_warehouse.tbl_abc
ALTER COLUMN first_nm type varchar(120);
The error in your syntax is that you missed a TYPE keyword:
ALTER TABLE data_warehouse.tbl_abc
ALTER COLUMN first_nm TYPE varchar(150);
and if you have a NOT NULL constraint you want to remove, add a new ALTER COLUMN inside the same ALTER TABLE statement:
ALTER TABLE data_warehouse.tbl_abc
ALTER COLUMN first_nm TYPE varchar(150),
ALTER COLUMN first_nm DROP NOT NULL;
for reference look here: https://www.postgresql.org/docs/current/sql-altertable.html
Edit: as in the comment, if you have a view which involves the same column, drop it and re-create it under transaction:
BEGIN TRANSACTION;
DROP VIEW [...];
ALTER TABLE [...];
CREATE VIEW [...];
COMMIT;
Be aware that to alter a table, you must acquire an exclusive lock on it, so during the whole process, all the queries over the same table and on the views of the table are locked, also if they don't read from the altered column (because the whole table is locked) - use with caution in production environment
I am trying to alter a column in my ingres DB to expand the size of the column.
The query i'm running is
ALTER TABLE test_table ALTER COLUMN address varchar(100) NOT NULL
Which gives error
Error: ALTER TABLE: invalid change of attributes on an ALTER COLUMN
SQLState: 42000 ErrorCode: 3859
Anyone any idea why I'm getting this error? I've checked the syntax for altering tables.
Probably you have NULL in data. Update your table first (set to empty string or any value you want):
LiveDemo
UPDATE test_table
SET address = '' -- or another value indicating missing addres like 'none'
WHERE address IS NULL;
And then try:
ALTER TABLE test_table ALTER COLUMN address varchar(100) NOT NULL;
EDIT:
If you don't want to enforce NOT NULL use just:
LiveDemo2
ALTER TABLE test_table ALTER COLUMN address varchar(100);
I'm trying to add an XMLType column into a table, but it returns an error. Why?
This is the query:
alter table TEST_ID add column xml_column xmltype;
It returns the error:
[SQL] alter table TEST_ID add column xml_column xmltype
[Err] ORA-00904: : invalid identifier
You don't need the "column" word in there, so it's:
ALTER TABLE test_id
ADD xml_column xmltype;
In addition,
you can add multiple columns at the same time with:
ALTER TABLE table_name ADD (column1 VARCHAR(40), column2 Date, column3 Number);
There is a syntax error- key COLUMN is not required before column name :
1. To add a single column:
ALTER TABLE TABLE_NAME ADD
COLUMN_NAME DATA_TYPE;
2. To add multiple columns:
ALTER TABLE TABLE_NAME ADD (
COLUMN_NAME1 DATA_TYPE1,
COLUMN_NAME2 DATA_TYPE2,
COLUMN_NAME3 DATA_TYPE3
.
.
.
);
I always get the error on postgres sql can anyone help me
ERROR: Syntaxerror in „(“ LINE 4: Liga_Nr int(1),
^
********** ERROR **********
ERROR: Syntaxerror in „(“ SQL Status:42601 Symbol:79
Here is my code
DROP TABLE IF EXISTS Liga;
Create Table Liga(
Verband varchar(90),
Liga_Nr int(1),
PRIMARY KEY(Liga_Nr)
);
DROP TABLE IF EXISTS Spiel;
CREATE Table Spiel(
);
DROP TABLE IF EXISTS Verein;
CREATE Table Verein(
);
DROP TABLE IF EXISTS Spieler;
CREATE Table Spieler(
PRIMARY KEY(Spieler_ID)
);
Integer types don't accept a parameter. The correct code is:
Create Table Liga(
Verband varchar(90),
Liga_Nr int,
PRIMARY KEY(Liga_Nr)
);
If you want to store a small number, use smallint. You can read about numeric types here.
