NJ/NX-series Database Connection CPU Units User's Manual (W527)
One of the information layers of each DB. Refers to the columns of each table.
Refers to a database in a server.
Refers to a virtual communication path established between CPU Unit and DB.
Used to connect a CPU Unit to a DB. This function operates on a CPU Unit.
Refers to special instructions for the DB Connection Service.
This service provides the DB Connection function to connect a CPU Unit to a DB.
In the ID information indication on the side of the CPU Unit and in Sysmac Studio, this service is
indicated as "DBCon".
Used to shut down the DB Connection Service after automatically saving the Operation Log files
into the SD Memory Card.
Means to assign each member of a DB Map Variable to the corresponding column of a table in
the connected DB.
Refers to a variable that uses a structure data type for DB access as its data type.
One of the Operation Logs. This log is used for recording which SQL statements are executed,
and parameters and execution result of each SQL statements.
Refers to EM Area of the memory for CJ-series Units. The data in this area are retained even if
the power supply to the CPU Unit is cycled (i.e. ON → OFF → ON) or the operating mode of the
CPU Unit is changed (i.e. PROGRAM mode ⇔ RUN mode).
One of the Operation Logs. This log is used to record the executions of the DB Connection
Service.
Used to trace the operations of the DB Connection function on the CPU Unit. There are three
types of Operation Logs; Execution Log, Debug Log, and SQL Execution Failure Log.
Used to switch whether to actually access the DB or to normally end the instructions without
accessing the DB when DB Connection Instructions are executed.
Refers to the memory area for storing the SQL statements in the Spool function.
Used to store some SQL statements for inserting records into the DB or updating the records in
the DB that could not be executed due to a network failure.
Refers to the SQL statements stored in the Spool memory.
Refers to structure data type where all or some of the columns of a specified table are registered
as structure members.
Stands for Structured Query Language, which is one of the languages for DB processing such
as data read/write.
One of the Operation Logs. This log is used to record execution failure of SQL statements in the
DB.
Refers to the statements that show a specific instruction used for DB operations such as data
read/write.
One of the information layers of each DB, which contains data.
