Both global and a are listed in your grammer under kwr rule.

kwr is mentioned in the inl rule which isn't used anywhere. So your parser don't know how to deal with inl and don't know what to do with two inl chained together (global a)

First issue: Is there another solution to this problem?

You current date is resolved per minute, so if you run your job more than one time during that minute, there would be already an job instance with the same parameters, hence the issue. Your ts parameter should have a precision of a second (or less if needed).

Second issue: How can I access the JobParameters within my reader? I want to pass in the file path as command line argument and then read this file.

You don't need that beforeStep method. You can late-bind the job parameter in your bean definition as follows:

It looks like you didn't intend on comparing an array to a number. What you want is to fetch the value from your result set. Since you only expect a single value there is no need for a while loop.

Looking at your command, an error occurred in the process of enrolling the admin client.
this process is a command that requests enroll from Fabric-CA, and Fabric-CA must be up.

However, in the case of the command ./network.sh up createChannel you entered, Fabric-CA is not up.
You need to add a parameter option to up Fabric-CA.

See the command usage for ./network.sh

What do you mean by outside? Do you want to pass parameters when running the script? If so, you can run the script with

From the test network documentation, "The deployCC subcommand will install the asset-transfer (basic) chaincode on peer0.org1.example.com and peer0.org2.example.com and then deploy the chaincode on the channel specified using the channel flag (or mychannel if no channel is specified)."

You should still be able to deploy your chaincode but you'll need to use the Fabric peer command directly instead of the test network scripts. The process is described in the Deploying a smart contract to a channel tutorial and there is more detail in the Fabric chaincode lifecycle documentation.

You are executing CTAS (CREATE TABLE AS SELECT) and the purpose of this query is to create the table with data which is generated via this query.

If you want to just execute the query and see the data then remove first line of your query.

The code "print(fps[n][3], fps[n+1:][3])" will first print element at index [3] of the sublist of element [n[ of the main/parent list. But after that, it'll print the remaining parent list as the code says "[n+1:]". The semicolon tells the program to take the list from element n+1 till the end. Instead, try running a nested loop to print a 1-many relation, something like:

I can see a couple of problems:

1. None of your preg_matches have an opening delimeter, e.g. you have: preg_match("^[a-zA-Z\s]*$/", this is missing a forward slash at the start, should be: preg_match("/^[a-zA-Z\s]*$/". This applies to all preg_matches so a error is thrown.

2. You have an incorrectly named variable, you have alphabetic_check($fistname, , should be $firstname as used elsewhere

Fixing those 2 and plugging in some valid data and your functions work fine.

May I suggest a slight change to the functions though that may make them easier toread, for example:
