SQL DDL to support migration and updates
sql,sql-server,sql-server-2008-r2,database-migration,ddl
Have you looked at Data Tools (also known as SSDT)? It's an add-in to Visual Studio that allows you to have (among other things) database projects. You add the objects in a declarative manner (i.e. create table, create procedure, etc) and the tool figures out how to make a target...
Is there a postgres command to list/drop all materialized views?

Show all: SELECT oid::regclass::text FROM pg_class WHERE relkind = 'm'; Names are automatically escaped and schema-qualified according to your current search_path where necessary in the cast from regclass to text. Materialized views in the system catalog pg_class are identified by relkind = 'm'. Per documentation: m = materialized view To...
Cannot add foreign key constraint mysql
mysql,sql,database,foreign-keys,ddl
A foreign key must reference a primary or unique key. For example, you could make countries.cname unique: CREATE TABLE countries ( id INT NOT NULL AUTO_INCREMENT, cname VARCHAR(45) NOT NULL, PRIMARY KEY (id), UNIQUE (cname) -- Here ) COMMENT='Country List'; Alternatively, you can drop the salt column and make the...
Do I need to move local index after table moved to different tablespace
sql,database,indexing,oracle11g,ddl
Defining an index as local has nothing to do with the tablespace it's stored on. local refers to partitioned indexes being partitioned in the same way the table they refer to is, as opposed to a global partitioned index which has its own partitioning definition (or even defined as nonpartitioned),...

error in SQL syntax creating a database table
index is a reserved word in MySQL (and any other relational database I can think of). It's used to create, well, indexes. In MySQL you can escape object names by enclosing them with ` characters: CREATE TABLE mytable ( tag MEDIUMTEXT, `index` BIGINT(20) ) ENGINE MyISAM; But it's generally considered...
Different triggers same job?
The two triggers work in the same way, except that the first will probably take more time. Suppose your test table has a table with a million records. And you attempt to update some column for every record. Then first the update operation will happen, and only once updates on...
Oracle - Transaction with a series of DDL statements
oracle,oracle11g,oracle10g,ddl
DDL statements in Oracle are each a transaction. Each DDL statement causes few or many changes in the data dictionary, like obj$. I am not sure, but looking at the major work Oracle has gone through to ensure that locking is not an issue with even the early versions of...

Single out specific parts of EVENTDATA for use in a DDL Trigger?

You need to bear in mind that an alter statement can add more than one column.

SQL trigger for expiration date
As Martin Smith suggested in the comments, a trigger probably isn't the best approach here. Instead, you could use a computed column, which is, in a nutshell, a column that has its value calculated ("computed") by some other columns in the table. In your case: CREATE TABLE my_table ( col1...

How to convert primary key from integer to serial?
postgresql,types,auto-increment,ddl,postgresql-9.3
serial is a pseudo data type, not an actual data type. It's an integer underneath with some additional DDL commands executed automatically: Create a sequence (with matching name by default). Set the column NOT NULL and the default to draw from that sequence. Make the column "own" the sequence. Details:...
Modify a column to remove or change default value in oracle 11g
Column C2 current definition: C2 date default sysdate When you're altering this column to VARCHAR2(10) there is no problem, because Oracle performs an implicit conversion of the values from DATE to VARCHAR2 using current NLS_SETTINGS (date string representation pattern for example) When you're altering the column to NUMBER(9) Oracle cannot...

Using a Materialized View, can you generate a Two-Timestamp view from a One-Timestamp table?
sql,sql-server,data-warehouse,ddl,materialized-views

This last restriction rules out using...
CREATE SCHEMA IF NOT EXISTS raises duplicate key error
postgresql,concurrency,ddl,catalog
This is a bit of a wart in the implementation of IF NOT EXISTS for tables and schemas. Basically, they're an upsert attempt, and PostgreSQL doesn't handle the race conditions cleanly. It's safe, but ugly. If the schema is being concurrently created in another session but isn't yet committed, then...

How is a data dictionary/table stored in memory?

Are there downsides for creating a large VARCHAR value in Redshift?
What do you mean "downside"? There is a really big downside if you don't make the column big enough -- you can't use it to store the values you want to store there. As for additional overhead, you don't need to worry about that. A varchar() type basically only takes...

MySQL FOREIGN KEY error, ON DELETE CASCADE
