I am trying to create a basic script that converts an Oracle script into a Sybase script.
The only things im changing are Datatypes and the to_char and to_date functions.
I am not really 100% sure of the way it works. I have tried running the functions through a loop to replace each word line by line but that didnt work.
If you could help me understand what I am doing wrong I would be very grateful.
Code:
#!/bin/bash
function menu()
{
echo "This program will convert Oracle syntax into SYBASE syntax."
}
function replaceDate()
{
cat $file | sed 's/TO_DATE/CONVERT/g' >> $newFile
cat $file | sed 's/TO_CHAR/CONVERT/g' >> $newFile
}
#Datatype conversion
function replaceWord()
{
cat $file | sed 's/VARCHAR2/VARCHAR/g' >> $newFile
cat $file | sed 's/NUMBER/NUMERIC/g' >> $newFile
cat $file | sed 's/DATE/DATETIME/g' >> $newFile
}
menu
read -p "Please enter the file name that you wish to convert: " file
read -p "Please enter the name of the new file: " newFile
replaceDate
replaceWord

mcxconvert
mcx convert(1) USER COMMANDS mcx convert(1)
NAME
mcx convert - convert between mcx storage types
SYNOPSIS
mcx convert <matrix-file-in> <matrix-file-out>
mcx convert [--write-binary] --cone-to-stack <cat-file-in> <cat-file-out>
mcx convert [--write-binary] --stack-to-cone <cat-file-in> <cat-file-out>
mcxconvert is not in actual fact a program. This manual page documents the behaviour and options of the mcx program when invoked in mode
convert. The options -h, --apropos, --version, -set, --nop, -progress <num> are accessible in all mcx modes. They are described in the mcx
manual page.
mcx convert [--cone-to-stack (transform cone file to stack file)] [--stack-to-cone (transform stack file to cone file)] [--write-binary
(output native binary format)] [--cat (read and write cat format)] [-cat-max <num> (limit the stack conversion to <num> matrices)]
In the two-argument invocation without additional arguments, mcx convert converts from the format found in the first file to the other for-
mat, i.e. from native interchange to native binary format or the other way around. When querying with the -q option, mcx{convert} will out-
put a one-line synopsis describing the matrix in the argument. The --cone-to-stack and --stack-to-cone options convert between the two types
of concatenated output provided by mclcm.
DESCRIPTION
The mcl libraries make extensive use of matrices. Matrices are used to encode graphs, matrices and clusterings. They can be stored either
in interchange or in binary format. The latter is somewhat more efficient in storage and much faster in both reading and writing, but the
default is interchange format.
The mcl input routines recognize the type of storage they are dealing with. If you want to convert a matrix to the other storage type, sim-
ply specify the file name of the matrix you want to convert. mcx convert will recognize its type, and write the other type to the file
specified as the second argument.
OPTIONS
--cone-to-stack (transform cone file to stack file)
This option requires two trailing options, the names of respectively the source cone file and the target stack file.
--stack-to-cone (transform stack file to cone file)
This option requires two trailing options, the names of respectively the source stack file and the target cone file.
--cat (read and write cat format)
-cat-max <num> (limit the stack conversion to <num> matrices)
--write-binary (output native binary format)
This option is only useful with either of the options --cone-to-stack, --stack-to-cone, or --cat.
