What is TimpleSQL?
TimpleSQL is a set of standalone procedures that helps the developer either quickly prepare values, or execute submission, for INSERT or UPDATE queries into a database using tclodbc.
TimpleSQL only requires a standard one-dimensional Tcl Array of your input values and the target table name/array where you want to insert or update your information. TimpleSQL gathers the target table's column name/formatting requirements and, depending on your desired action, will generate the proper SQL input string based on the matching indexes in your Tcl Array. You can also Validate your submission data relative to the target table before submission (recommended).
TimpleSQL can either prepare and execute the submission of the generated SQL, or you can use some lower level commands to help you generate SQL structures (e.g., SELECT, INSERT, UPDATE) for hard coding SQL in your own applications.
Using TimpleSQL, you can quickly database enable standard Tcl/TK and CGI Applications for things like submission forms, polls, and shopping carts.
QUICK EXAMPLE: INSERT Record into Database (uses tclodbc)
# Load the Pacakges
package require TimpleSQL
package require tclodbc
# Connect to the database
database db MyDatabaseName
# Submission data that you create in your appliation/CGI.
# - The Array Index Values are the Target Table Column Names
set arr(FName) John
set arr(LName) "Doe's last name"
set arr(State) Anywhere
set arr(ZIP) 12345
set arr(AddToMailingList) 1
set arr(submitDate) [[clock format [[clock seconds]] -format %m/%d/%y]]
# Generate the Table Column Type Cross Ref Info
GenTableColTypes typTbl tbl_RegistrationInfo
# Validate the Submission Value Formats to the Target Table Formats
if [[catch {ValidateSubmissionData arr typTbl} err]] {
# Data is NOT Valid - Report Errors
foreach item [[join $err]] {
puts "ERROR: $item"
}
} else {
# Data is Valid/Compatiable with Target Database - Insert Record
TimpleSQLInsert arr typTbl
}
# Disconnect from the Database & Exit
db disconnect
exitOTHER FEATURES:
UPDATE Database Records: TimpleSQL can also do record updates using the same basic approach and supports straight SQL Instructions! For Example:
if [[catch {ValidateSubmissionData arr typTbl} err]] {
# Data is NOT Valid - Report Errors
foreach item [[join $err]] {
puts "ERROR: $item"
}
} else {
# Data is Valid/Compatiable with the Target Database - Update the Record \
TimpleSQLUpdate arr typTbl �FName = �Dave��
# Note: A standard �WHERE� SQL Condition is at the end of the command. This is passed \
to the command so that the SQL UPDATE can modify the proper record/records in the database.
}
Record Existance Checking: The EntriesExist Command in TimpleSQL produces a Tcl boolean response based on your submission array and table. This is quite handy for CGI, Login Screens, etc.. For Example:
# Validation Contents
set arr2(LoginName) buba
set arr2(LoginPasswd) buba1
# Generate the Table Column Type Cross Ref Info
GenTableColTypes typTbl tbl_LoginVerification
if [[EntriesExist arr2 typTbl]] {
# Login OK
} else {
# Login Failed
}
Dynamic SQL Generation: You can also use TimpleSQL for dynamic SQL Generation, if you choose not to use the TimpleSQLInsert or Update Commands.
