### RapidIdentity Connect supports parameterized queries.
For example, in each iteration of the forEach loop, log
the user 's name to be their first and last name
separated by a single space. Parameters (params) could
be used in the example above as follows.
sql = "SELECT fname,lname,status FROM usr WHERE ID = ?"
users = queryDatabaseSQL(outputDB, sql, [user.fname + " "
user.lname, user.id
])
tableDef = createTableDefinition("usr", "id", "native",
"fname,lname,status")

### RapidIdentity Connect supports parameterized queries.
For example, in each iteration of the forEach loop, set the
user 's id field value to be their first and last name
separated by a single space. Parameters (params) could
be used in the example above as follows.
updateSQL = "UPDATE usr SET name = ? WHERE ID = ?"
result = updateDatabaseSQL(outputDB, updateSQL, [user.fname + " "
user.lname, user.id
])

# Input from text file
textInput = openDelimitedTextInput("/root/senators.csv",
"LastName,FirstName,Title,Email,Phone,Description")
# Define table and open DB connection(MySQL w / auto - increment)
tableDef = createTableDefinition("senators", "id", "native",
"lastname,firstname,title,email,phone")
outputDB = openDatabaseConnection("com.mysql.jdbc.Driver",
"jdbc:mysql://server/dbSchema", tableDef, "root", "password")
# Loop through input records
forEach(inputRecord, textInput) {
# Schema mapping
renameRecordFields(inputRecord, "LastName,FirstName,Title,Email,Phone",
"lastname,firstname,title,email,phone")
# Check for existance in target
queryRecord = createRecord()
queryValue = getRecordFieldValue(inputRecord, "email")
setRecordValue(queryRecord, "email", queryValue)
matchingRecords = getDatabaseRecords(outputDB, "senators",
queryRecord)
if (matchingRecords.length == 1) {
# Match found.Add primary key to current record from source.
matchingKeyValue = getRecordFieldValue(matchingRecords[0], "id")
setRecordFieldValue(inputRecord, "id", matchingKeyValue)
} else {
# No match found.Nothing more to do.
}
# Write(insert / update) record to database
saveDatabaseRecord(outputDB, "senators", inputRecord)
}
# Close database and file connections
close(outputDB)
close(textInput)# Input from text file
