You can insert data from tables in any accessible database:
Tables in either the IQ store or the catalog store of the database you are currently connected to.
Tables in an Adaptive Server Enterprise database.
A proxy table in your current database, that corresponds to a table in a database on a remote server. For details, see Chapter 4, “Accessing Remote Data” and Chapter 5, “Server Classes for Remote Data Access” in the System Administration Guide: Volume 2.
You can insert data easily from an Adaptive Server Enterprise or SQL Server database, using the LOCATION syntax of the INSERT statement. You can also use this method to move selected columns between two Sybase IQ databases.
To use this capability, all of the following must be true:
The Sybase connectivity libraries must be installed on your system, and the load library path environment variable for your platform must point to them.
The Adaptive Server Enterprise server to which you are connecting must exist in the interfaces file on the local machine.
You must have read permission on the source ASE or Sybase IQ database, and INSERT permission on the target Sybase IQ database
Inserting data directly from Adaptive Server Enterprise
Connect to both the Adaptive Server Enterprise and the Sybase IQ database using the same user ID and password.
On the Sybase IQ database, issue a statement using this syntax:
INSERT INTO iq_table
LOCATION 'ase_servername.ase_dbname'
{ SELECT col1, col2, col3,...
FROM owner.ase_table }
Issue a COMMIT to commit the insert.
When Sybase IQ connects to the remote server, INSERT...LOCATION can also use the remote login for the user ID of the current connection, if a remote login has been created with CREATE EXTERNLOGIN and the remote server has been defined with a CREATE SERVER statement. For more information, complete syntax, and an example, see INSERT statement in Chapter 1, “SQL Statements,” in Reference: Statements and Options.
Sybase IQ does not support the Adaptive Server Enterprise data type TEXT, but you can execute INSERT...LOCATION (Syntax 3) from both an IQ CHAR or VARCHAR column whose length is greater than 255 bytes, or a LONG VARCHAR column, and from an ASE database column of data type TEXT. ASE TEXT and IMAGE columns can be inserted into columns of other Sybase IQ data types, if Sybase IQ supports the internal conversion. Also note that INSERT...LOCATION does not support the use of variables in the SELECT statement. By default, if a remote data column contains over 2GB, Sybase IQ silently truncates the column value to 2GB.
Users must be specifically licensed to use the Unstructured Data Analytics functionality. For details, see Unstructured Data Analytics in Sybase IQ.
You may substitute curly braces {} for the single quotation marks that delimit the SELECT statement. (Note that curly braces represent the start and end of an escape sequence in the ODBC standard, and may generate errors in the context of ODBC.)
If you need to load larger data, see Bulk loading data using the LOAD TABLE statement.
For details on the syntax of the INSERT statement, see Chapter 1, “SQL Statements,” in Reference: Statements and Options.
The following command inserts data from the l_shipdate and l_orderkey columns of the lineitem table from the Sybase IQ database iq11db.dba on the server detroit, into the corresponding columns of the lineitem table in the current database.
INSERT INTO lineitem
(l_shipdate, l_orderkey)
LOCATION 'detroit.iq11db'
{ SELECT l_shipdate, l_orderkey
FROM lineitem }
The destination and source columns may have different names.
The order in which you specify the columns is important, because data from the first source column named is inserted into the first target column named, and so on.
You can use the predicates of the SELECT statement within the INSERT command to insert data from only certain rows in the table.
This example inserts the same columns as the previous example, but only for the rows where the value of l_orderkey is 1. Also in this example, the TDS packet size is specified as 512 bytes.
INSERT INTO lineitem
(l_shipdate, l_orderkey)
LOCATION 'detroit.iqdb'
PACKETSIZE 512
{ SELECT l_shipdate, l_orderkey
FROM lineitem
WHERE l_orderkey = 1 }
