TheBlobssample shows you how to create a BLOB stream for reading and/or writing the value of a specificBLOB fieldon a specific record. To this end, the sample uses theCreateBlobStreammethod ofTFDQueryto create a read-only BLOB stream. In this sample, the BLOB stream is used to read the picture contained on eachBLOB fieldof each record of…
To this end, the sample makes use of the following properties and methods ofIFDPhysTransaction:
TheIsolationproperty, which is used for setting up the transaction isolation level for the transactions that FireDAC…
TheBlobStreamssample shows you how to use theBLOB streamingtechniques of FireDAC. To this end, this sample implements both theexternal streamingand theinternal streaming.

The sample demonstrates how to use theTFDQuerycomponent in order to set upmaster-detail relationshipsbetween datasets. It uses the master-detail relationship to automatically filter a detail dataset based on a current master dataset record. In this sample, the master dataset has “Order” records, and the detail dataset shows only lines for the current order.
FireDACrepresents a range type column as aftADTfield with 3 subfields:
lbound– lower range bound.hbound– upper range bound.flags– range flags.
Note: Columns of range type are read-only. This sample updates…
This sample shows how to redirect inserting, deleting and updating records using standalone table adapter.

This sample implements a multithreaded application, where each thread uses theIFDPhysConnectioninterface to establish a connection. The multipleconnection establishmentsmay lead to performance degradation across the whole system. To avoid this, you can enable thePooledproperty to use theconnection pooling.
