declare a local variable and use it in your fileUploadField control.

code for file upload field:

a!fileUploadField(
label: "Document",
labelPosition: "ABOVE",
target:cons!C_FLD_document,
value: local!loadedFiles,
saveInto: local!loadedFiles,
validations: {}
)

put the below code in your button saveInto:

saveInto: {
a!forEach(
items: local!loadedFiles,
expression: {
a!save(ri!loadedFiles[fv!index].fileAttached, fv!item)
}}

-----------------------------------------------------------------

ri!loadedFiles: is your CDT where you are loading the files.

fileAttached: a column in your CDT

Thanks! 

But I do not know what to put to replace
local! loadedFiles
fv! index

it would be like this?

 a!fileUploadField(
 label: "Document",
 labelPosition: "ADJACENT",
 /*maxSelections: 1,*/
 value: ri!newDo.docum,
 saveInto:
 {
 a!forEach(
 items: ri!newDo.documentation,
 expression: {
 a!save(ri!newDo.documentation[fv!index].fileAttached, fv!item)
 }
 ),
 ri!newSoli.documentation,
 ri!newDo.docum,
 a!save(ri!newDo.day,now())
 },
 target: cons!C_FLD_document,
 validations: {}
 )

Try this inside button:

this will create a separate row in database for each file attached

saveInto: {
a!forEach(
items: local!loadedFiles,
expression: {
a!save(ri!loadedFiles[fv!index].fileAttached, fv!item)
}

}

Your query is not so clear.

Do you want to store the documents into KC and store their docId into Appian?

Or, are you trying to store the documents directly into the DB? Because file upload fields are not meant for serving this. This allows you store the documents into Appian KC and later you can store the docId's into the Database.

Are you trying to refer to Blob?

What do you mean when you say you have a field to upload files to a database?

The file upload field allows you to upload documents into Appian.
