Transaction block processing for conditional commit databases

A method for a database, comprising:

• receiving a transaction request comprising one or more transaction blocks in an order
• evaluating, using a processor, each transaction block of the one or more transaction blocks in the order by:
• determining in the order whether a condition expression of a transaction block of the one or more transaction blocks is true, wherein the condition expression includes an expression inquiring whether all of the value have stayed the same before a calculation phase, and wherein in the event that all of the value have not stayed the same before the calculation phase, retrying the condition expression before performing the calculation phase;
• and
• in response to the condition expression of the transaction block being true, adding in the order one or more associated action sets of the transaction block to a transaction context;
• and
• in response to each of the transaction blocks being evaluated, causing the transaction context to be executed as an atomic transaction.

A computer program product for a database, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

• receiving a transaction request comprising one or more transaction blocks in an order
• evaluating, using a processor, each transaction block of the one or more transaction blocks in the order by:
• determining in the order whether a condition expression of a transaction block of the one or more transaction blocks is true, wherein the condition expression includes an expression inquiring whether all of the value have stayed the same before a calculation phase, and wherein in the event that all of the value have not stayed the same before the calculation phase, retrying the condition expression before performing the calculation phase;
• and
• in response to the condition expression of the transaction block being true, adding in the order one or more associated action sets of the transaction block to a transaction context;
• and
• in response to each of the transaction blocks being evaluated, causing the transaction context to be executed as an atomic transaction.
