Package nzgo is a pure Go language driver for the database/sql package to work with IBM PDA (aka Netezza) In most cases clients will use the database/sql package instead of using this package directly. For example: nzgo defines a simple logger interface. Set logLevel to control logging verbosity and logPath to specify log file path. By default logging will be enabled with logLevel=Info and current directory as logPath. You can configure logLevel and logPath (i.e. log file directory) as per your requirement. There is one more configuration parameter with logger "additionalLogFile". This parameter can be used to set additional logger file. additionalLogFile can be used to enable writing logs to stdout, this can be achieved by simply setting "additionalLogFile=stdout" Valid values for 'logLevel' are : "OFF" , "DEBUG", "INFO" and "FATAL". logLevel=OFF can be used to turn off logging. It will turn of both internal and additionalLogFile logs. These logger configuration parameters should be mentinoed in connection string. The level of security (SSL/TLS) that the driver uses for the connection to the data store. onlyUnSecured: The driver does not use SSL. preferredUnSecured: If the server provides a choice, the driver does not use SSL. preferredSecured: If the server provides a choice, the driver uses SSL. onlySecured: The driver does not connect unless an SSL connection is available. Similarly, Netezza server has above securityLevel. Cases which would fail: Client tries to connect with 'Only secured' or 'Preferred secured' mode while server is 'Only Unsecured' mode. Client tries to connect with 'Only secured' or 'Preferred secured' mode while server is 'Preferred Unsecured' mode. Client tries to connect with 'Only Unsecured' or 'Preferred Unsecured' mode while server is 'Only Secured' mode. Client tries to connect with 'Only Unsecured' or 'Preferred Unsecured' mode while server is 'Preferred Secured' mode. Below are the securityLevel you can pass in connection string : Use Open to create a database handle with connection parameters: The Go Netezza Driver supports the following connection syntaxes (or data source name formats): In this case, application is running from NPS server itself so using 'localhost'. Golang driver should connect on port 5480(postgres port). The user is admin, password is password, database is db1, sslmode is require, and the location of the root certificate file is C:/Users/root31.crt with securityLevel as 'Only Secured session' When establishing a connection using nzgo you are expected to supply a connection string containing zero or more parameters. Below are subset of the connection parameters supported by nzgo. The following special connection parameters are supported: Valid values for sslmode are: Use single quotes for values that contain whitespace: A backslash will escape the next character in values: Note that the connection parameter client_encoding (which sets the text encoding for the connection) may be set but must be "UTF8", matching with the same rules as Postgres. It is an error to provide any other value. database/sql does not dictate any specific format for parameter markers in query strings, but nzgo uses the Netezza-specific parameter markers i.e. '?', as shown below. First parameter marker in the query would be replaced by first arguement, second parameter marker in the query would be replaced by second arguement and so on. nzgo supports the RowsAffected() method of the Result type in database/sql. For additional instructions on querying see the documentation for the database/sql package. nzgo also supports transaction queries as specified in database/sql package https://github.com/golang/go/wiki/SQLInterface. Transactions are started by calling Begin. This package returns the following types for values from the Netezza backend: You can unload data from an IBM Netezza database table on a Netezza host system to a remote client. This unload does not remove rows from the database but instead stores the unloaded data in a flat file (external table) that is suitable for loading back into a Netezza database. Below query would create a file 'et1.txt' on remote system from Netezza table t2 with data delimeted by '|'.
