I have a hive table, I want to add column into it.
Query is :
ALTER TABLE maineventslog ADD COLUMNS (test_column int) CASCADE;
I am getting below error :
FAILED: SemanticException [Error 10006]: Partition not found.
Why column is not getting added. Hive version is Hive 1.1.0-cdh5.4.0
Why do you need to have CASCADE there. Following command should work :
ALTER TABLE maineventslog ADD COLUMNS (test_column int)

The solution is to set a default value for the column. Then you can define the column as NotNull.
Like this
ALTER TABLE temp_test_persons
ADD COLUMN newSuperColumn SUPER NOT NULL
DEFAULT '';
ALTER TABLE temp_test_persons
ADD COLUMN newSuperColumn SUPER;
Is it possible to add multiple columns in a single Alter query in Redshift
Alter table employee
add column Name,
add column Age,
add column Salary
According to Redshift Documentation, You can add only one column in each ALTER TABLE statement. Only way to add multiple columns is executing multiple ALTER TABLE statements.
I have a table named "well_all", which is in a schema named "staging", postgresql.
Its data is from a csv, the table doesn't have "id" field. I wanted to add "id" field in the table. So I did:
ALTER TABLE staging.well_all ADD COLUMN id SERIAL PRIMARY KEY;
But I am getting an error:
"well_all" is not a table, composite type, or foreign table
So, I'd tried to add "id" field simply:
ALTER TABLE staging.well_all ADD COLUMN id INTEGER NOT NULL;
But getting the same error, too.
I checked the database exists in that schema. It exists.
Is this something you faced before? Would you like to help me to solve this problem?
I have a previously created table and I am trying to make the Primary Key, which is BookingID, auto increment. I have 4 records in the database currently. The SQL function keeps telling me there is a syntax error near ' ALTER' . I am using SQLite if that matters.
ALTER TABLE Booking AUTO_INCREMENT=5
Because "alter" in SQLite only lets you rename tables or add columns; it doesn't support what you're trying to do.
For more information, check out the documentation of ALTER TABLE in SQLite:
SQLite supports a limited subset of ALTER TABLE. The ALTER TABLE command in SQLite allows the user to rename a table or to add a new column to an existing table.
I need to add a unique field index to an existing table. I made this row:
ALTER TABLE auth_user ADD UNIQUE INDEX (email);
The table and the field are already exist.
The error is:
Query Error: near "UNIQUE": syntax error Unable to execute statement
What am I missed? Did it have any specific requirements for SQLite3?
CREATE UNIQUE INDEX IF NOT EXISTS MyUniqueIndexName ON auth_user (email)
Also, read the official manual:
