I modified the add VW_ section. When I run it as sh -x scriptname <dbname> <source_schema> <target schema>
the output on screen is exactly what I want but the files generated is not the one. I am missing the output of files somewhere .
##############################################################################
#checks if the file has view in it

cat $TN.${ecmdate}.sql | grep -i 'view'
if [ $? -eq 0 ]
then
VW_VAR=` cat $TN.${ecmdate}.sql | grep -i view | awk '{print $3}' | cut -d '.' -f2 `
echo " VW_$VW_VAR "
sed -e 's/'${VW_VAR}'/VW_'${VW_VAR}'/g' $TN.${ecmdate}.sql > $tmpfile_cln
cat $tmpfile_cln
# cat $tmpfile_cln > $TN.${ecmdate}.sql

db2_prepare
DB2_PREPARE(3) 1 DB2_PREPARE(3)
db2_prepare - Prepares an SQL statement to be executed
SYNOPSIS
resource db2_prepare (resource $connection, string $statement, [array $options])
DESCRIPTION
db2_prepare(3) creates a prepared SQL statement which can include 0 or more parameter markers ( ? characters) representing parameters for
input, output, or input/output. You can pass parameters to the prepared statement using db2_bind_param(3), or for input values only, as an
array passed to db2_execute(3).
There are three main advantages to using prepared statements in your application:
o Performance: when you prepare a statement, the database server creates an optimized access plan for retrieving data with that
statement. Subsequently issuing the prepared statement with db2_execute(3) enables the statements to reuse that access plan and
avoids the overhead of dynamically creating a new access plan for every statement you issue.
o Security: when you prepare a statement, you can include parameter markers for input values. When you execute a prepared statement
with input values for placeholders, the database server checks each input value to ensure that the type matches the column defini-
tion or parameter definition.
o Advanced functionality: Parameter markers not only enable you to pass input values to prepared SQL statements, they also enable
you to retrieve OUT and INOUT parameters from stored procedures using db2_bind_param(3).
PARAMETERS
o $connection
- A valid database connection resource variable as returned from db2_connect(3) or db2_pconnect(3).
o $statement
- An SQL statement, optionally containing one or more parameter markers..
o $options
- An associative array containing statement options. You can use this parameter to request a scrollable cursor on database servers
that support this functionality. For a description of valid statement options, see db2_set_option(3).
RETURN VALUES
Returns a statement resource if the SQL statement was successfully parsed and prepared by the database server. Returns FALSE if the data-
base server returned an error. You can determine which error was returned by calling db2_stmt_error(3) or db2_stmt_errormsg(3).
EXAMPLES
Example #1
Preparing and executing an SQL statement with parameter markers
The following example prepares an INSERT statement that accepts four parameter markers, then iterates over an array of arrays con-
taining the input values to be passed to db2_execute(3).
<?php
$animals = array(
array(0, 'cat', 'Pook', 3.2),
array(1, 'dog', 'Peaches', 12.3),
array(2, 'horse', 'Smarty', 350.0),
);
$insert = 'INSERT INTO animals (id, breed, name, weight)
VALUES (?, ?, ?, ?)';
$stmt = db2_prepare($conn, $insert);
if ($stmt) {
foreach ($animals as $animal) {
$result = db2_execute($stmt, $animal);
}
}
?>
