For each column in a row of the result, the name of that column is used as an index in to array and the value of the column is stored in the corresponding array entry. If two or more columns in the result set of a query have the same name, then the last column with that name will overwrite prior values and earlier columns with the same name will be inaccessible.
If the array variable name is omitted or is the empty string, then the value of each column is stored in a variable with the same name as the column itself. Tcl variable names can appear in the SQL statement of the second argument in any position where it is legal to put a string or number literal.
The value of the variable is substituted for the variable name. If the variable does not exist a NULL values is used. If it has only a "bytearray" representation, then the value is inserted as a BLOB. When the SQL is contained within double-quotes " But TCL will never substitute a: The "close" method As its name suggests, the "close" method to an SQLite database just closes the database.
This has the side-effect of deleting the dbcmd Tcl command.
Here is an example of opening and then immediately closing a database: So the following code is equivalent to the previous: The transaction is committed when the script completes, or it rolls back if the script fails.
If the transaction occurs within another transaction even one that is started manually using BEGIN it is a no-op. The transaction command can be used to group together several SQLite commands in a safe way.
Also, BEGIN does not nest, so you have to make sure no other transactions are active before starting a new one. The "transaction" method takes care of all of these details automatically.
The syntax looks like this: The default is deferred. The "cache" method The "eval" method described above keeps a cache of prepared statements for recently evaluated SQL commands.
The "cache" method is used to control this cache. The first form of this command is: The upper limit is The default is If you set the cache size to 0, no caching is done.
The second form of the command is this: The "complete" method The "complete" method takes a string of supposed SQL as its only argument.How can I change an SQLite database from read-only to read-write?

How can I change an SQLite database from read-only to read-write? When I executed the update statement, I always got: SQL error: attempt to write a readonly database.
The SQLite file is a writeable file on the filesystem. Last month I started a guest post on initiativeblog.com demonstrating the steps required to use HUE + with the Hortonworks Data Platform (HDP); I’ve used HUE successfully with HDP and , and have created a step-by-step guide on using HUE with HDP below.
I’m participating the Insight.
